So yesterday was errand day & he slept in the car/pram no worries (grrrrrr) but once home would not go down. At about 8pm I started feeding him up and by 9:30 he had had 2 240ml bottles. Rocked him to sleep for 1/2hr while waching Medium and he stayed asleep when I put him in the cot, yippee.

Thanks for the help, Im feeling a little more optimistic and will be taking him to sleep school soon.
