MumofLewis- My DS also wakes early around 6am and play until 8am has a short nap for 20-30minutes and then doesn't go down again until around 10/10.30am after he has had a bottle. I must get into the habit of letting my DS play by himself before going into get him...
My DS has had a temperature too but no sign of teeth.. he only has 2 teeth s far!! Hopefully the rest will come through soon. When did your DS's top teeth come through? I keep thinking my DS's are on their way through but then nothing.
