As of this week my DD ages 2 has spent every weekday morning with my mum (nana) since I went back to work (9am-1pm) when she was 10 months old. This week she has started with a childminder one a Wednesday and Friday and both days I have been to pick her up she has been naughty. On Wednesday she threw toys and yesterday she pushed another child over. She's not normally like this and knows it's wrong as she tells me what she's done as soon as I pick her up. Could it just be her testing the boundaries with the childminder??
