My 2.9 yo old ds is lovely most of the time but lately his behaviour has really deterioriated. He's started biting his best friend at nursery and whenever he's asked to do anything he either ignores you completely or shouts 'NO!'. He does this to any adults and DH and I are getting really fed up and embarrassed by it all.
We want to nip this in the bud before it gets worse and our first step is to try and find a book to guide us through these hideous toddler years. Can anyone recommend anything that's been tried and tested with dealing with toddler tantrums and bad behaviour?
