She’s probably potty training her, getting ahead of the restMy thoughts exactly. There’s no way a baby her age would stand up and in the living room and nobody would notice. This is the kind of thing that happens with a 2/3 year old you are trying to toilet train who’s running around the place with no nappy on - why would a 1 year old be left alone with no nappy on for long enough to do a poo you wouldn’t even notice? Doesn’t add up at all.
Plus why do they never ever have a top on that child in the pool or in the sun. Truly shocking!
