Tummy troubles with formula?
My LO is 3 and half weeks old and we just transitioned him to full formula from being full breast milk since he was born. With breast milk, he pooped almost every single feeding but now with formula he poops maybe once a day. During feedings though he is constantly pushing which frustrates him because nothing comes out. Is this normal? When he does poop it’s not hard. Is this his tummy getting used to the formula?
