What It's Really Like Having Your Second Baby (From A Mum Of Two)

Bringing home your second baby is a completely different experience to your first. You’re not stepping into the unknown anymore – you’ve already lived through the newborn stage with those sleepless nights and feeding challenges, you've done the emotional "what the hell am I doing" rollercoaster bit of becoming a parent. But what no one really tells you is that having a second baby brings an entirely new set of curve balls.

From being pregnant with a toddler to navigating sibling dynamics and juggling two very different sets of needs, life with two children is beautiful, but chaotic. I now have two little ones (Mila, three-and-a-half, and Apollo, who is now 8.5 months old) and the transition from one child to two has been one of the most emotional, exhausting and rewarding experiences of my life.

If you're wondering what having your second baby is really like, here’s my honest experience.

Being Pregnant With a Toddler Is a Whole Different Ball Game

When I was pregnant with my first baby, I had the best time. I napped whenever, wherever, I put my (swollen) feet up, ate ice cream without sharing, and binge-watched anything I wanted to, for as long as I wanted. Being pregnant the second time around? Absolute mayhem.

At the time, my daughter Mila was 2 years and 9 months old, and as the default parent she relied on me for everything — play time, bath time, bedtime, snacks, cuddles, all of it. As my pregnancy progressed, there were days when I was completely exhausted and physically struggling, but she still wanted my full attention. That relentless desire for attention is sweet, of course, but on top of the physical, mental and emotional experience of pregnancy, it's also a lot to bear.

That said, there were also incredibly wondrous moments. Mila would kiss my belly, press her ear against it and talk to her baby brother. Those little interactions gave me all the feels and made pregnancy the second time around feel really special in a different way.

The Newborn Phase Was Surprisingly Easier The Second Time

One of the biggest surprises after having my second baby was that the newborn stage actually felt easier. With my first baby, Mila, the newborn phase was a real challenge. She barely slept and I felt like I was constantly learning on the go. By the time Apollo arrived, I felt much more prepared. I had all the “tricks of the trade” up my sleeve and felt confident navigating newborn life.

Ironically, I barely needed them! Apollo was a much more "textbook" newborn. If he cried, it usually meant he was tired or hungry, and once we figured that out, things were pretty straightforward.

I also had a much smoother labour with my second baby, which made a huge difference to my mental state and physical recovery. That alone made those early newborn weeks feel much more manageable.

Balancing Two Kids Takes Time (And Patience)

The biggest adjustment wasn’t actually the baby, it was helping Mila adjust to becoming a big sister.

At the beginning, she couldn’t understand why I didn't just put the baby down and play with her, or make her lunch immediately. She's not a spoiled child, she was just used to being the only priority. When I was breastfeeding or settling Apollo, she had to wait – something that feels incredibly unfair to a toddler who previously had my undivided attention.

There were definitely tough moments. The crying and tantrums from her, frustration and a lot of guilt from me. I felt torn between the two of them and questioned whether I was doing enough for either child.

But slowly, things shifted. Mila started to get used to Apollo being around, and began taking on little “big sister” responsibilities. She loved helping with him and feeling included in his care.

Now, eight months later, her little brother is her biggest joy. Watching the way she cares for him, plays with him and lights up when she sees him honestly feels like my greatest life accomplishment.

Breastfeeding Was Harder Than I Imagined

One thing I didn’t expect to struggle with so much the second time was breastfeeding. I wasn’t able to breastfeed Mila, and it was something I had always felt a little sad about. When Apollo arrived, I was determined to try again and give it my best shot.

With a lot of persistence, I managed to breastfeed for seven months. But it definitely wasn’t easy. I had two rounds of mastitis, blocked milk ducts that needed draining and eventually only one breast producing milk. I pushed as far as I could, but eventually had to stop. Even though it didn’t go exactly how I had hoped, I’m really proud of how far I made it.

The Toddler Routine Curveball No One Talks About

One thing I honestly hadn’t thought about at all before having my second baby was the impact on my toddler’s routine.

When you’re pregnant, so much of the focus is on labour, postpartum recovery, feeding and how your first child will adjust emotionally. But the small everyday logistics caught me completely off guard.

Things like bedtime routines suddenly becoming chaotic, figuring out how to get everyone out the door for kinder, or missing a swimming lesson or bath because the baby needed something. The day-to-day of life was unexpectedly stressful, more than I had imagined it would be.

A newborn changes the entire rhythm of a household, and toddlers thrive on routine. We got there in the end, but it took time for us to find a new normal that worked for everyone.

The Baby Product That Saved My Sanity

With a toddler and a newborn, time is your most precious resource. One product that genuinely became a lifesaver for me was a hands-free breast pump. With Mila running around, I simply didn’t have the time to be attached to a wall pump while expressing milk. The wearable design meant I could pump completely hands-free while still doing everything else, like making Mila breakfast, giving her a cuddle or reading her a book.

After my difficult breastfeeding experience with my first baby, having something that made expressing easier took a huge amount of anxiety off my shoulders. It truly became one of my favourite baby products the second time around.

The Best Part of Having Two Kids

If there’s one thing that makes every challenging moment worth it, it’s watching the relationship between your children grow. Seeing Mila step into her role as a big sister and the love she has for Apollo is something I could never have imagined before becoming a parent of two.

Yes, life is busier. Yes, it can feel chaotic. But it’s also fuller, louder and more joyful than I ever expected. And honestly? I wouldn’t have it any other way.
