Gas & Constipation

Angie • All in God`s perfect time!

My 10 day old son has been experiencing severe gas pains since about 4 days old. I changed his formula to Similac Total Comfort about 3 days ago and ha hasn't had a poop since. He still have the gas, mostly at night and I'm concerned now that my change in formula has him constipated.

Is there anything that I can give him to make him poop? Any suggestions on how to deal with the gas? Do I stay on the new formula or revert back to the old one?
