kacy is starting to do the same, i have some thing simlar to a naughty spot but its for kacy to calm down and for me to calm down before i shout at her, its called my bottom step, i put her their until she has calmed down then we have cuddles, but if she has been naughty i do tell her. she has been their for an hour before, but she did calm down when she realised that i wasn't bothered i just carried on doing whatever i was doing.
when i'm out is a different story, i have tried different things and i found this works the best, this has happened, me and my mum and sister were in a shop and kacy was walking we went down the toy bit and she saw a toy that she has got and she wanted to stand their and play with it, she did for a minute while me and kris were looking at something, then she started screaming when we were leaving, first off all i walked away and left her but that has stopped working now she jsut goes back and plays, so i got her hand went down to her level told her that we were leaving and walked her out the shop, she was screaming blue murder, so i went to a courner outside and bent down and just stayed their with kacy in front of me until she calmed down, then we had hugs and carried on.
sorry if that doesn't make sense but i hope it helps.
