Dd just 7 has been constipated all wk until today but not suffering with overflow. It's pretty constant and messy. I've found some pull ups that I've put on her as she was getting distressed soiling her pants. She's had a warm bath & now in pull ups & jim jams but still with a tummy ache. Does it normally last long? She's only had it a few times before & never during school time. They have PE tomorrow & don't want her to be embarassed if anyone spots her dirty undies.
