oh green poor little linc being sick,there nothing worse.
i would keep letting him play if thats keeping him happy might bounce some boogers out of him lol.
as for the feeding bit ,i just feed charlie a bottle when eva she wants one mostly 3-4 hourly but through the night she only gets one bottle and thats usually about 4-5 am, apart from this she sleeps all night now and if by chance she does wake up NOPE NO BOTTLE i give her the dummy put sooky back up near her face flip her over and thats it,shes been doing this routine for a few weeks now,i have a smalll lamp in her room i turn that on and make no eye contact with her at all otherwise she laughs her head off lol.
i tried very hard with this routine and at first it was a bit hard but now its bed at 7.30pm and awake at 7.30am with 2 very good sleeps through the da sometimes 3.
i sure hope he works him self out soon hun makes life so much easier
