2 year old wakes up at 5:30am

My daughter is 2 and goes to bed around 7pm to 7:30. She is dead tired by that point and floppy in our arms.

But then she wakes at 5:30am.

I have to leave for work at 5 so my dad (her grandfather) gets her and takes care of her until my fiancé wakes up at 7:30 (afternoon shift at work).

I feel TERRIBLE that my dad has to look after her for so long on his own. I guess it’s a lot of mum guilt and my own anxiety.

How do I deal with this situation?

Is it possible to make her sleep longer or do I just have to get over it?
