'Violent child' 'deliberate act' ?? some of the phrasing on this thread is awful.
I am the mother of a biter, there I said it. Baby, yes the baby, is 21 months old and we have signed several incident forms with regards to the matter. I always concerned for the welfare of any child who is bitten, but nursery staff assure me that this is phase that many kids go through, because lo and behold, they are not quite able to articulate their communication any other way, just yet.
She has also, on occasion bitten me, my husband and her 7 year old brother. Shall I just exclude her from family life until she "learns". No of course I won't! Like nursery, a firm no and minimal fuss as on-going attention may encourage the behaviour. As her vocabulary improves the incidences have lessened and I imagine will continue to do so. On going biting and a child may be experiencing other developmental difficulties and perhaps need additional assessment and support.
I am sorry OP that your child has sustained a marks that have lasted two weeks, that's a pretty lengthy bite and perhpas there are supervision issues in the room? However as others have acknowledged, it is a well known stage that some babies and toddlers go through, so I would consider it a risk of this type of child care, my son on the other had was on the receiving end when he was around the same age. He was and is fine, BTW.
I don't think we can exclude them from the setting, on the grounds that this would not be of any long term benefit as isolation won't teach them how to intercat, will it? I can't believe how quick some are to label and blame a small child that is only just learning the nuances of relationships and interacting.
