Hang in there...it will get better!
By 26 months mine were both sleeping from 7:00 to 7:00. BUT until then they literally did not sleep through the night.
We no longer had naps at that age and I also started using the "Okay to wake" clock. That thing has made the biggest difference to how long they sleep in. I am the worlds meanest mother because now that they're 5 and 3 I set it for 9:00 am on weekends They don't sleep til then but they dont dare leave their rooms until the clock says its okay.
