So we gave Grayson his daily vitamin for the first time that the doctor told us to give him, and my baby who usually eats and sleeps very well since he was born was so fussy last night. :( And what seems to me to be a little constipated because he normally poops a lot, and hasn't pooped like he normally does. (I keep a log on how long and when he usually eats and when he poops and pees since he's breast fed) I'm thinking about not giving him the vitamin until I can speak to his doctor. :l have any of you other mommies got a reaction like this to a daily vitamin with your babies ? He just finally ate for his usual amount of time this morning and is content asleep (thank goodness)
