So you have a night owl, God Bless. We had a couple of night owls too and wow, hope I can help.
First, at night when she wakes up, try changing her and feeding her in a dimmly lit room. Strong light tells most bodies, even ours, that it is time to get up and do something.
Second, dont let her cry it out, not for another three months or so. They cant sooth themselves until that age and stage of 6-8 months or so.
Then, try to stay calm, if you get overly excited or agitated, that could feed her energy.
And last, if she wakes easily during the day for some play, then wake her and play. A few naps are good, but they are disturbing the night. She might be a little irritated, at first, but she will come around and realize you are a better play mate during natural day light hours.
If you are at home with her, hope you are napping with her. But not too long, cause then both of you will be in that habit and maybe you arent the night owl type.
I am and it was still hard because my second child was the night owl and I was exhausted from all day with son one. It felt like they tag teamed me, but I loved it and wouldnt wish for any other way.
Hope I helped,
M.
