DD is nearly 6 months and is a really good sleeper but recently she is waking at 6am and sometimes earlier. I don't need to get up til 7am for work. I give her her last bottle at 8pm and she is normally asleep by 8.30 and doesn't wake in the night. I keep increasing her feeds but it doesn't seem to make any difference. She sleeps between 2 and 3 hours per day (whenever she's tired - no nap routine).
Does anyone know any ways to get her to sleep a little longer or is this just normal?
