So, a positive update.
Dh is working nights--so I am on my own with the kids. I borrowed one of the BW books from the play center...and read the chapter about being consistent, a good wind down etc...It actually made me realize I had let bed time get a bit wild ie, jumping around and chasing eachother. So I spoke to DS (who is 6.5) before dinner about how we needed to have quiet time-reading etc from after bath to bed...and thats just what we did.
She did try to get out--but only once- and she never actually got out. I used very few words, when I had to resettle her--and she's asleep! That took less than 20 minutes! Yippeeee!
