Little girl is 2.5. Really good speech/communication etc. attempted to start potty training - tried bare bum tried some little knickers. She will not entertain the toilet or the potty. Screams NO if I suggest it and gets herself all worked up as if she’s scared. When she has an accident sometimes she will acknowledge it other times just carries on about her day. I’m at my wits end.. never done this before and don’t even know how best to approach it. She will hold her wee in for as long as possible and I don’t want her getting a sore tummy. It’s like she’s almost scared of the potty. When she needs a wee she will shout for a nappy on but will not even sit on the potty/toilet…
