I have a 32-weeker and he is now almost 7 weeks old (39 weeks adjusted). I swear his little life revolves around pushing/grunting constantly trying to poop or toot. He doesn't sleep comfortably because he is always grunting and pushing so hard. He is breastfed and formula-fed. He's not constipated but you'd think he is with all this grunting and pushing. I just feel bad for him and wish I could help him be more comfortable. Is his normal for preemies? Anything I can do to help him be more comfortable?
Try giving him gas drops. Or talk to his pedi about changing to a sensitive formula or changing your diet for bf'ing to see if it may help.
