Thanks to all for you commenrs and suggestions.
I have started to put him down straight after seeing tired signs and he attempts to go to sleep, but then cries and as soon as I pick him up he falls asleep in my arms. Then I can put him down for about 40 min. I think it might be getting better.
BUt his reflux is playing up, so I have an dr. appointment monday to get that looked at.
And to top it off today I've come down with a terrible head cold - so I am struggling to get up and feed DS. Lucky husband had the day off and was able to let me sleep in.

Thanks
PS DS is an august bub - I look at the august 07 buddies
