Just as title says really. Our 3.5 yr old is sometimes overly affectionate. He will go up to babies/toddlers he doesn't know and touch their faces etc. or try to hug his friend from nursery when she has said she doesn't want a hug. He also keeps trying to put his hand down my top (a hangover from when I used to breastfeed, which I've always said no to). We explain about consent etc all the time, but he just keeps returning to the behaviour and asking why. Any advice? Thank you
