Only you can put a time limit on it. What is your sanity (and the other kids) level? How long can u last? If ur close to losing it, term her but if u can and want to work with her more then do it. It's only you that knows how long u can go. I went two wks once with a screamer then termed him. Last yr I went 4mths with a crier. The only reason I lasted 4 mths was because he ate and napped well for 3 hrs. But after 4 mths of still coming in every morning crying and crying through everything we did I termed him. I termed the other boy quicker just after two wks because he didn't nap didn't eat didn't want me to pick him up he just screamed and screamed and nobody got time for that!
