I know this is normal behaviour up until the age of 2ish, but 12.5mo DD puts stuff in her mouth she knows she's not supposed to. By knows she's not supposed to, she'll often look at me before she does it, sometimes shake her head and then do it anyway. Not so dangerously are baby wipes, but she also takes every chance she can get to lick the soles of my shoes and put stones in her mouth. Obviously I tell her not to and like I say, she'll shake her head because I'm saying no but she's not disswayed. I really don't know what to do because I've been telling her no for months, these aren't new things. I don't want to shout at her and scare her but I'm concerned there'll be an occasion I'm not quick enough. She still mouths absolutely everything and it's not teething, she's always been this way. Oh and she will actually eat the bits of baby wipes or paper, etc she gets hold of.
