Has anyone ever had any issues w/ LOs sleep patterns and attitude changing after starting iron supplements? Ever since we started giving them to him he has essentially stopped sleeping and, he is refusing to let me put him down in his crib! He loses his mind and cries uncontrollably and he's back to waking every 2 hrs with one nap that's less than an hour a day. WTF?!?!? He's essentially inconsolable. He had 4 teeth come in a once a few weeks ago, and it was never this bad.
I've also taken him to the Dr and had his ears checked to rule out an infection. The Dr says he's the picture of health besides his low iron. I don't know what to do!!! I'm about to lose my mind! The ONLY change in his routine is the iron drops so I really don't know what else it could possibly be that's causing this behavior out of nowhere. #halp

Re: Iron supplements & mood/sleep changes
I don't have any experience with this, but can't vitamin D cause constipation? Have you tried gas drops?
How long has this been going on? Maybe you could stop the drops for a few days to see if he improves. If he's better, then maybe discuss alternatives with the pedi? Good Luck.
