So the history is, DD1 has made a little friend at nursery this little girl we shall call A, A is a year younger than DD1 but about 9 months older than DD2 although she will be in the same year at school as DD2. Anyway we found out that she lives a street away and she has been coming round with her Mum and younger sister every week or we go round to theres, I have got quite friendly with the Mum and the younger sister is lovely.
A is very demanding though, the first time she came in she demanded the TV on (we don't have it on during the day), she whinges and cries a lot as well. Anyway it's obvious that she only wants to play with DD1, DD2 is being totally left out, they were really nasty to her today, calling her names and shutting the bedroom door (it's DD2's room as well), every 5 mins DD2 was coming in saying "A called me X, A scratched me (she did) then A bit her not hard but it did leave a mark). The Mum did keep telling A off but it had no effect whatsoever, I told DD1 off for it as well. The thing is A is not a nice little girl really I know that's a terrible thing to say but for instance I said who wants an ice lolly they all said "ME" of course, A started screaming she wasn't getting one and I said of course you are, then she said "I want the biggest one, DD2 I'm getting the biggest one, you aren't getting one" this happens all the time.
I don't know what to do or how to broach the subject with her Mum she obviously knows theres a problem as she said she had told A to behave when she came round today, my options are a) don't tell them to come round or go round but then I miss an afternoon of adult company b) send DD1 round to play by herself and keep DD2 here c) try to work at including DD2 in their games but it's hard as there is a 12 mo and 18mo to entertain as well d) tell DD1 to include DD2 more but to be fair it's really A that's the instigator not DD1, DD1 and 2 play well together as it is.
Any advice, sorry for the essay but I cannot have DD2 getting bit. Oh DD1 is 5 and DD2 is 3 1/2
