Not every baby poops every day:) pooping every 24-36 hours is actually quite normal. If she’s not in discomfort, you can actually leave her be and let her poop on her own.. but if she’s straining/in discomfort and having a hard time pooping, a massage/gripe water/lifting her legs may help. Oh for my baby, when I lifted her legs when she was about 2-3 months old, besides pooping, she would also throw up.. so look out for that. May not happen in yours..
