My DS is 17 weeks and is becoming increasingly more constipated. He was always an every 3 day pooer but it now becoming every week. We are now on day 7 with no poo. He is being fed on demand with 1 bottle of formula at bedtime. With my 1st DS when I ate strawberries he was always guaranteed to poo. But they jave no effect with DS2. I've tried giving him diluted apple juice with no effect. I don't want to give him extra water ect as he should be getting enough fluid from my milk. Just wanted to know if there was anything I could eat which might help him poo?
