I have a biter.....but only at nursery

[Airfryer]

I'm at the end of my tether with this. My ds is 14 months and has been going to nursery since he was 8 months. He loves it there and is generally a very happy and loving little boy. But he seems to bite at nursery. He doesn't do this at home. They say he does it for no apparent reason and have a book detailing what has happened during the day to look for clues as to why....but they can't pin point it.

Some weeks I'll have a form every day to sign, and then other weeks he's really good and I think it's all over.

I went to pick him up today and when I went in he was crying. They explained he was having a time out because he'd bitten so I said I'd leave them for a bit to finish it off so that I didn't undermine their effort. When I went in, the form said he was sitting with another child and bit his face repeatedly, drawing blood. Apparently the blood was due to scratching. I was so disappointed I started crying.

I just don't know what to do about this and I feel terrible that he's doing this repeatedly. I know he's only young and that this is probably a phase but its just so hard hearing what he's been up to day after day.

Nursery have said that he is a very happy boy, is very affectionate with other kids and that this behaviour doesnt match his personality at all.

Has anyone had similar experience? Any ideas on how to deal with this. It's difficult as he's not doing at home but nursery seem to be doing everything they can and discipline is same there as at home

This might sound a bit simplistic but a book (recommended on here I think) called Teeth are not for Biting worked almost instantaneously with my DD. She was only biting me and one of her cousins but it was up to 10 times a day if at home. She was a bit older - just 2 - so understood the book, but definitely worth a go.
