My 16 month old son Ikaia has recently been waking up between 12:30am - 1:50am and crying hysterically for 15-45 minutes. About 4 of 7 nights a week. My husband seems to think it is gas, and/or constipation. Could this be the result of him eating more solid foods? Or could it be that he is still drinking from a bottle at night? Is there anything that I can give him for gas and/or constipation so that if this is the culprit, I can ease his pain? And so that my neighbors do not get us kicked out of our flat? HELP
