Waking up too early!?

My 10 month old will usually wake up around 4am, we give her a bottle and she will go back to sleep until about 6:30-6:45am. Which I have felt was pretty good since she goes to be by 7:30 every night. Over the weekend my husband and I had work commitments on Sun that had us up by 5:30am, which woke her up by 6am. Since then she's been up by 6am or earlier! it's been getting earlier by the day, today she was up by 5:45am and would not go back to sleep. She was grumpy and so tired this morning. What did you do to help your baby sleep in a little longer. I know kids usually get up early in general, i'm not expecting her to sleep until 8 or 9 but 5:45am is tooooo early for this moma!
