DS1 is nearly 3 - a sweet friendly and loving little boy most of the time. He has a fairly healthy varied diet and generally watches less than an hour of tv a day. Recently he's starting acting up a little bit (which I'm putting down to testosterone surges and a little brother arriving recently) and in particular he's started ignoring when adults ask him or tell him to do something - me, his dad, his nanny, his swim teacher, playgroup teacher etc. He will just carry on doing what he's doing and I find you have to just keep repeating to him until he confirms he's heard what you said - which can take 10 minutes or so sometimes. I'm hoping this is normal toddler behaviour which he'll grow out of by the time he starts school - as if he doesnt god only knows how he'll focus at school in a large class of 30 kids. Anyone have any thoughts?
