When getting ds undressed for the bath on Friday I found he had a really heavy red/ purple bruise on his upper arm (would have been through two layers of clothing) that looked like a bite mark. No accident etc mentioned by nursery although they did say that he kept waking up from his nap crying and they couldn't work out why - judging from the bruise it must have really hurt possibly was keeping him awake.
I understand that the staff can't watch all the children all the time, toddlers do bite and hit and they must miss stuff like this, and am very happy with the nursery, but am feeling a bit emotional about it as it is such a bad bruise so am wondering whether to say anything and if so what... what would you do?
