Hi all. My 3 week old DD seems to be having tummy troubles. Currently on aldi mamia formula. She poops every couole days and it is soft when she passes it, but seems to reallt struggle to pass it and is having pains the day before/the run up to having the poop. Will nap for 5 minutes then wake up screaming. Would changing milk help this issue or do i just need to give it a bit more time? Thanks
