T.L.
I took my daughter to the emergency room when she was about 2 months old for what i thought was constipation (it ended up being colic) anyways the drs told me to try using a rectal thermometer, as gross as this is going to sound, put it in just a tiny bit and move it around very gently. if that doesnt work they told me to use suppositories, you can get pedia lax at walmart, they're huge yes, so break off a tiny piece and use that (those REALLY work) or you can try 2 oz of straight water and 1/2 an oz- 1 oz of apple/prune juice or feed him prunes. hope something helps him soon
