2.5 year old all of a sudden hitting, what to do?

My usually very kind 2.5 year old daughter now hits me when getting her ready for bed. I grab both hands and firmly say “we do NOT hit, it hurts me and makes me sad”. Usually when we get ready for bed we brush teeth, new diaper then watch a little bit of a movie then she goes in her crib. Nights that she hits I tell her she’s going right to bed right after brushing teeth and changing diaper. that’s it no movie. Now here’s what makes it difficult, she laughs when she does it AND aftersays “I sorry”. But she keeps doing it, almost as if she thinks just saying sorry afterwards makes it ok.Any advice? via /r/Parenting http://ift.tt/2pltL1O
