My son is just turning 17 months old and has become a biter. The main offenses happen when he is at nursery. He attends 3 days a week from 8am until 6pm. I am aware that some children can go through a biting phase and there are many causes of this. He has been teething, he also gets a little bity when he is over tired or frustrated. We also believe there may be a little bit of attention seeking thrown in there as well. We went through a stage where he had bitten 9 children in the space of 2 days. We thought we were getting past this stage as the biting seemed to calm down and we had a couple of weeks without incident. However we are starting to get a few incidents again happening, not every day at nursery but at least once a week. We have had discussions with the nursery on what they are doing and what we can do to try to help at home. On the most there seems to be no apparent cause or trigger for the biting. We have steps in place at nursery that if he does they tell him no that he shouldn't bike and remove him from the situation. the bitten child receives a lot of attention then. My child is very inquisitive and does not want to sleep when other things are happening around him to the point he goes of the day without sleeping until he literally falls asleep no matter what he is doing. As over tiredness is affecting this as well we have steps in place with the nursery to try to help him get regular naps so he does not become over tired. I am concerned now however as my child was given a final warning yesterday that if this continues they would have to expel him from nursery after a parent had put in a formal complaint. My son adores all the staff and they adore him to and he is very settled there as he has been attending since he was 5 months old. I really need some more advise on what we can do in this situation.
