It could be her milk, my baby was drinking the blue Newborn Enfamil that they give in the hospital and that gave my baby the worst constipation and gas omg...i switched her to purple Gentlease and now she's gas free

It takes several weeks maybe even months for the bellies to not have gas. I had an all plant based diet drank tons of water and my son still had gas it's totally normal. If it's still like that at 3m I would worry but for now baby is fine I'm sure just getting adjusted to life. @nashyresto,
