My 18 month old ds has recently started slapping my face when he is frustrated or upset - normally when I have told him no to trying to eat a whole tin of biscuits or when out walking, picking him up to cross the road as that is where he decides to sit and view the scenery! I realise this has alot to do with his frustration as he is desperately trying to talk but has anyone got any tips on how to manage this? Im using my firm 'NO' but Im worried that he will do this to someone else, plus it is embarrassing while out and about.
