My baby is 2 weeks 2 days shes on gerber gentle.

This is my 4th baby but first time exclusively formula feeding and was wondering if its normal that she only poops maybe once or twice a day?

And also when she's pooping i see her straining alot she gets really really red and is making all this grunting noises while pushing. Is all that normal? Or is the formula causing her to strain. Im actually gonna call her pedi tomorrow for some advice as this really concerns me idk if im over reacting or if its normal but i need some peace of mind 😞

One more last question, she passes alot of gases and feewwww are they really stinky 😂 is that also normal? Part of formula feeding. Sorry to much questions
