at baby's age is pretty normal. formula can cause constipation. just make site you're keeping track of how many dirty diapers she has. with breastfeeding babies they don't poop as much bc their body's use most of what is given in the milk.
yea just give him/her warm bath tummy rubs and feet massages theres a specific foot massage for constipation i use it all the time on my 7 month old
