DD won't poo in her nappy and holds on until her nappy is off for changing. It started when she was 7 and a half months and has been going on for over a month now. It's completely puzzled the health visitor and me as babies aren't supposed to have bowel control that early apparently. It does make disposing of the poo and wiping her bum much easier but I'm worried she'll do herself some damage by holding on as she can't tell me she needs to go. Has anyone else ever heard of this happening at this age or do I have the youngest anally retentive child? Any ideas or advice, anyone.(Help!!!)
