Oh man! I truly feel your pain... I think that with every little on it differs and you did the right thing.... Just leave her be and she will eventually fall asleep and hopefully stay asleep.... I wish I could give you a time line BUT i am sooo the wrong person to ask about this.... Noah is still NOT sleeping through the night!
We let her put herself to sleep last night, it took about 35 min but she finally did and she sleep until 5 when she awoke I lefct her for 10 min and she was out again, and was up at 6:15. I think we just have to let her be, nap time too, which is hard b/c she is with my sis and MIL.
She does have 2 teeth but I think the top ones are cutting through.
For hayden it lasted a few nights in a row, and then she was fine. During the day or before bed is she getting a good amount of time to "stand" - so she wears herself out? With Hayden I eventually let her learn how to get herself back down - the first night of this I went in a bunch of times, the next night - it was up to her! And as for her naps - even if she was WIDE AWAKE, I'd have her stay in her crib at least 30 mins during the nap time. GOOD LUCK.
Has she cut any teeth yet? Maybe this is also impacting things?
