I feel your pain, dd1 2.7 is exactly the same, its a complete nightmare, she wont stay in the double buggy, or the buggy board, she hid in a display kitchens cupboard in B&Q, she puts things under the buggy when i'm not looking, gets into window displays, generally just screams tho whole time we are in a shop, last week she had a massive massive tantrum in Lakeside, when I tried to pick her up off the floor, she threw herself down, putting her tooth through her lip, everone was staring and muttering at the cruel mum that had hurt her dd
