MyDS turned 1 at the weekend. He has bitten DH and I for past 2-3 months, usually on the cheek or chin but occasionally on our arms. Initially we thought it was teething, but that has all settled down for a period and the biting persists. He has biten us much less recently, but since starting at the Child minder 3 days a week he has bitten one of her other mindees twice recently, and this evening she has been called over to their house to discuss this.
When he bites us we say oww firmly and put him down, which upsets him but he doesn't seem to relate the two. The other child is 14-15 months, so it is difficult to get him to do anything fixed in response.
We have tried to pin point when the biting occurs. It doesn't appear to be tiredness or frustrated behaviour. I have seen him crawl over to other friend's babies with his mouth open heading for their face/head and managed to divert his crawl away before he engages. If anything I would say it appears to be when he is a happy/excited mood and the child minder feels this is the case as well.
I know this may just be a phase he is going through, and he is too young to 'time out', but am really worried other parents are angry. Could they request that my DS has to leave the CM? He loves going there and she is flexible for my crazy hours and I feel very 
thinking that we may have to move him
