My DS is really affectionate but recently whilst kissing and snuggling he's sunks his teeth in- it's agony and on a few occasions he's bruised me. The other day at soft play he did it to another baby. I've been sternly saying 'no' and putting him down away from me/other for a moment before returning to him and saying something like 'we don't bite/say sorry' My worry is he is so little and doesn't know what he's doing or mean to do it- he thinks he's kissing. I know I have to nip it in the bud pronto but is this the best way? I'm worried that he'll stop kissing/snuggling as a consequence. Any tips?
