since my LB was one week old, i've been suplementing with formula (Isomil 1) coz my breast milk didn't seem to be enough for him. but since the beginning of this week (he's 3 weeks old now, hes been constipated, he only pooped 3 times the entire week and he pushes and grunts till he's red in the face and sometimes on his nammy we'll see a liitle poop stain, so it's like he was really trying to poop but couldn't. he even wakes up at night crying.
