Hello, I'm a FTM. My little guys is 3 weeks old. I think he may have a sensitivity to the formula I have been giving him. He's been on Similac Advance since birth because that's the formula he was given at the hospital. He has become quite fussy over the last week or so. He will scream for hours after he eats. I have tried everything to try and stop what I believe is tummy discomfort. I burp him after every few mils, I've given him gripe water, massaged his tummy, bicycled his legs, put him on his belly and rubbed his back, given him a warm bath etc. Nothing seems to help him. Last night he was so bloated after he ate I couldn't even put his diaper on him properly. He screamed and cried for 2 hours. I should also add that he hasn't been pooping like he usually does. He might have 1-2 good poops a day unlike before when he was having anywhere from 8-10 good poops. It looks like he is trying with everything he has to poop, but he may only get a little drop out. I don't know what I can do to help ease his pain... one more thing I forgot to add. He gets about 2 ounces of breastmilk a day. Unfortunately that's all I can produce in the run of a day. Any advise is welcome 😞 TIA.
