Hi all, my little girl who is almost 5 months hasn’t pooped in 4 nearly 5 days! I’ve tried everything, watered down prune purée, cool boiled water, massages, baths, laying on her tummy, bicycle legs etc, she’s been on formula and breast fed, and usually poops once or twice a day, her farts smell vile and she screams when she farts and her stomach is hard, I feel so bad but I don’t know what to do?! She also has been prescribed lactulose and has been taking it each night but it’s not doing a thing :-(
