Ive dealt with some of these :

- people putting a dummy back in your child's mouth (but you can see they just touched the bit that goes in their mouth and you know they didn't just wash their hands) Just take it straight away when you see ehats happening and give bub a new one ( We never used Dummies anyway)

- offering your child food you don't want them to have (Just say they arent old enough/ allowed to have it , you are the parent

- playfully teasing them in a way that they think is ok (no malice intended) but that you aren't ok with (eg playfully calling a chubby kid 'fatty' or something like that) : Childs name is not fat hes s big boy like his Dad, Or Shes not chubby shes curvy like mum etc Change a negative for a positive

- letting their older children touch a baby when they are sick etc - Just keep them away

- disciplining your child ( Alot of people wont discipline someones else child and if they know you and you dont discipline then they should respect your limits on that. We dont discipline or punish and when Nanny (my mum) says shes going to smack him ........I always say then mummy will smack Nanna because Smacking is naughty And Nanna gets the point... until next time
