Hi, Every lo is different but i think that i might be inclined to feed at that time but then put back in his cot and persit with that. Is that 11p, feed a df? or does he wake? If he wakes then feed 15-30mins before he is due to wake. The nwing's i would just sh/pat till the morning.
Its going to probably be quite hard, so make sure you are ready for it and try and get dh/dp to help out too so as he knows his not getting a feed from him. The first night is the hardest but as the nights go by it WILL get easier. When we did this i think it took 1.5 hrs (not constant crying) to get him back off on 1 nwing then 2hrs later another 45mins but after 2-3 nights he was sleeping through again.
