I don't want to gloat but my baby started sleeping through at 8 weeks.
Rather than yet another thread of mums moaning that their's don't sleep through how about a thread of those that do, since our routines may be helpful to others.
My DS is FF and suddenly started sleeping through all by himself at 8 weeks. Its not every single night yet, but most nights. I'm hoping this lasts as long as possible!
I'm not sure if it was anything I did, but we had just started putting him into Grobags which may have had something to do with it. Also he gets a last feed at 1030pm-ish, and I try to get him to drink as much during the day as I can, so that hopefully he's not so hungry during the night. The only routine we've established so far are the 7pm, 1030pm and 7.30am feeds, the rest of the day is a little hit and miss, but feeding every 3-4 hours, depending on how much he wants. DS naps when he wants during the day, usually just power naps as I haven't managed to get him to take regular daytime naps yet. Some days he'll nap more than others. We're gradually getting into a full routine, but still working on it!
