4 months today and sleep has gone crazy - any suggestions?!

[leo1978]

Ds has never slept through the night which I have no prob with - usually down at 7-8ish, used to have an 11.00 which I stopped recently, as he was still feeding at 3 and then at 6.30.
Last night though, he went down at 7.30/8ish - woke up at 2.20 - wouldn't feed, lay with me in bed till 3.30 and then fed - then was awake until 5 - cooing, gurgling, playing and then shouting.
What in the world is going on with this small boy?

no advice but extremely interested in the answer...

Me too, my DD (5 mths) is doing the same - bed at 7, feed at 11, used to sleep through till 6, now is up 3-5am, playing and chatting v loudly. Have tried weaning her in last week or so, as she is quite big & hungry girl. She's not teething either, two just come through and no sign of the others. Just a (short) phase I hope.
