this may not be a popular opinion but sometimes there isn't anything more you can do to make them sleep for longer. my DS is just over 17 months & pretty much woke every 2 hours until around 16.5 months - now he will sometimes do 4-5 hours at the start of the night (and then back to around every 2 hours) but sometimes still wakes every 2 hours. a good night for us is 3 wake ups but 5 is normal.

i tried so many things when he was little to try & stretch out sleeps. i thought we'd cracked it at around 3 months when he would sleep for 5 hours at the start of the night. the longer sleeps were in the pram - he slept in it till he was about 4 months old from memory. it was great because when we heard him stirring a little, we could rock him & he'd go back to sleep without waking. then he worked out how to roll & went back to waking frequently as he'd roll & wake himself up - in the cot by this stage.

sometimes i think i'm losing the plot & other times i think i can keep doing this indefinitely - or at least until he's ready to sleep for longer (which i really, really hope is before he starts school ). i could try non-gentle parenting techniques but i don't like them & my gut feeling is that DS probably wouldn't respond anyhow.

sorry - my intent wasn't to make this about me, but just to say that i really think babies sleep longer when they're ready. my MG is a good example - they've all been so different & even the great sleepers have bad nights when teething or sick. but they've all starting sleeping longer at different times & it's a mixture of BF & FF & parenting techniques no one thing seems to have meant success!

i hope it improves for you soon, in the meantime grab rest where you can & make sure you have some 'me' time
