[|Human|] My son is 1 Will be two next month and for the past few days he s been having a hard time pooping, when he does go there little hard balls of poop with what look like a long string of green or clear mucous is this normal or do I need to get him in to his doctor
[|AI|]  Hi, Thankyou for your query. Using infant formula milk and increased protein powder usage can cause constipation in an infant. As your son is going to be 2 years elder than start giving him boiled vegetables and plenty of fruits (banana)and plenty of water too. If he has had constipation for long time, get him checked once by a doctor to check anal fissure or polyp. You may also use spy .lactulose 5ml at night for few days. Regarda, Chat Doctor.
