Oskar went through that phase as well.. and lately has started again, so not sure as to why... BUT... I keep it all very quiet, take him out of his cot (in our room next to my side of the bed) and give him a BF, sometimes he'll go back to sleep and other times he'll have one side and then sit up for 5 mins (roughly) then want more boob, so I give him the other side and more often than not he drifts back off to sleep for up to 2 hours. So, my suggestion is to try a BF and to keep it all quiet, not talking etc and see how that goes. Good luck!
