DD2 usually cries and carries on before she goes to sleep even when i am rocking her so i decided to put her down in her cot and let her cry or a while. she went to sleep after about 5 mins of crying. (and yes it did get pretty hysterical but as i said she does that sometimes even when i am holding her and rocking her to sleep). she woke up after about 40mins and started crying again. my question is.. what should i do then. let her cry for 5 mins til she goes back to sleep or just get her up and try rocking her to sleep again? i thought if they put themselves to sleep they will sleep through the first sleep cylce cause they know how to get back to sleep themselves?
