The second night she cried for less than 5 mins.
The third night there were no tears at all!
So happy this transition has been nice and smooth. So far no problems at all! In the mornings, we hear Millie get out of bed and start playing. We try to get downstairs before she starts crying out to make sure she knows that we aren't going to leave her in there forever. So far, it's working out great! We are very lucky to have a good little girl.
