my 2 month old has been sleeping a lot more in the last couple of days. he has been really struggling with gas, and only has a bm, but an explosive one, once a day or every few days. until then, he seems pretty grumpy. today was an explosion day, and he seems very sleepy. he is pretty much sleeping through the night, but he is feeding less frequently and for a shorter period of time - sometimes only 5-8 minutes. i just wondered if anyone else is experiencing the same thing and whether or not i should worry. my doctor has me giving him vitamins with iron, and i'm wondering if it's causing him some problems.
