I switch DS to Enfamil AR (added rice) for spit up a few days ago. He's spitting up less, however...he hasn't pooped since Wednesday night. He doesn't seem in pain, he's eating well, but I did notice him drawing up his legs in the crib last night.

It's the weekend, or I'd probably call the peds office. I suppose they have an answering service. I tried giving him a little water, but he didn't want it. I have bicycled his legs, given him a bath, and the thermometer trick. He's 4 months, so I guess he's too young for juice. What would you do?
