Gave my 6 month old a suppository and its been 30mins and still no bowel movement he strained then feel asleep?

Constipation : Constipation is a common problem. If he is comfortable leave him be. Babies may not have adequate abdominal musculature to push. Pull his knees to his chest and stimulate his rectum with a thermometer. Try pear juice which you can mix with water if you like. Give him a variety of fruits (esp fruits with pits) and vegetables. Cut down on his cereal/starches. Change of formula can help.
