Let’s talk about co-sleeping — something that’s been practiced for centuries and is still a natural, instinctive choice for many parents today. What’s really amazing? A mother’s body is literally designed to co-sleep.

When you sleep close to your baby, your body responds in incredible ways:

Prolactin (the milk-making hormone) increases, supporting breastfeeding through the night. Oxytocin (the love hormone) rises, helping you feel calm, connected, and in tune with your baby. Cortisol (the stress hormone) tends to lower, making sleep more peaceful. Your sleep becomes lighter and more responsive, keeping you in sync with your baby’s needs.

Even your brain changes. After becoming a mother, the amygdala — the part of your brain linked to emotion, vigilance, and survival — becomes more active. This is what makes you hyper-aware of your baby’s cries, movements, and needs, even in your sleep. It’s biology’s way of keeping you on alert to protect your child.

Now for a personal note: Alice kinda forced me into co-sleeping. I’m so wired to jump into action the second she cries — her crying physically makes me react! It just made sense to have her in bed with me, where she felt safest. And once she figured out breastfeeding? Oh my gosh, night feeds got soooo much easier. Total game changer.

Co-sleeping isn’t for everyone, and safe sleep practices are a must — but if you’ve found yourself pulled in by instinct, you’re not alone. Your body and brain were literally made for this.
