Problem with poop

Hi Ladies,

Since birth my son has really problem to poop by himself. He is suffering every day and I need to help him evacuate it. He is fully breastfed but if doesn’t poop everyday then he can poop like 200 grammes.

We went to hospital already when he was 2 weeks old but they didn’t find anything (except they always Confirmed his Intestines are full)

Do you have someone similar proble or do you know how I could help him?

We do massages, warm in the belly, exercises with legs.... nothing is helping.

Due to fullness of intestines he is having reflux as everything presses on the stomac

Thank you
