Since I have started weaning my 6 month old her sleep pattern has completely changed. she has always had her last bottle around 10.00pm and slept through until 8.00am in the morning no problem, but as soon as I started weaning her she can't seem to stay awake past 7.00pm after her bath, and then wakes up at 4.00am. I have tried dream feeding around 10.00pm but she still wakes up. Is this normal?
