My D.D (2.5yo) is very boisterous- loves rough and tumble, tickling games etc. She has a new baby brother and has dropped her nap since he arrived and the over-tiredness means she's getting giddy and hysterical and can end up upsetting other children - and today hurt another child at playgroup. I'm doing lots of praising of her when she is gentle but wondered if anyone new of any good books about being gentle/ kind. She absolutely loves story time so I am hoping this could help reinforce the message...
