DD1 (2y 8m) started nursery 3 mornings a week a couple of weeks ago and is loving it but I'm sure she's become naughtier at home since starting - in fact naughty isn't a word I'd've used of her behaviour till now. It's mainly manifesting itself in agression towards DD2 (12m), and general perverseness and tantrummy behaviour.
Anyone else gone through this? Tell me it's a brief phase!!
