My 9.5 month old daughter spends a lot of time with her almost 4 year old and 19 month old cousins. Therefore I think she's used to playing a bit rough. Today she played with her second cousin who is 13 months and was grabbing at her face, smacking her and even pushed her over :-( at 9 months, I really don't think it was intentional at all but I really want her to stop, especially as she's going to daycare next month! She also bites us which needs to stop. Does anyone have any suggestions on how we can encourage her to play nicer?
