Also, I still give them a sippy of whole milk to go to sleep at naps and bed time and they're 20m old so no help there. It was never a battle I was willing to fight, I need bedtime to be as easy as possible.
Breastfeeding to sleep is the biological norm and not a (bad) habit. Even if you are not breastfeeding, allowing an infant to drink a bottle or use a pacifier to suck is an method of soothing & a reflex.
Sounds like they're in their 6 month regression 🫶🏻 hang in there mama. Ride the wave and it'll end when it ends
