My dd is 2.5 years and goes to nursery 3 days a week, where i also work ( in another room). There have recently been a number of incidents, includind a lot of biting! that has caused other parents to complain about her! One parent says she's making her dd cry and "bullying" her!! - She's 2 for sake! It's really upsetting me and i don't know how to deal with it and what I'm doing wrong. Why is she so loud and in our face?
