"I certainly wouldn't stop night feeds at this age, as he's close to weaning and so needs as much as poss."
Advice on (and even understanding of) getting babies to sleep through the night is very different here in France to what I hear from friends in UK. Here we are told that waking in the night after the first couple of months is NOT because of a physical need for food but a HABIT to be changed. [Having lived in a Muslim country before, I actually understand this, because I have seen daytime fasters get used to waking up and eating at 2 AM for a full month, and then still waking up with grumbling tummies for a couple of days after fasting month was over. They go back to sleep without eating and after a couple of days body "forgets" that habit.]
When DD was 4 months old and still breastfeeding three times in the night, her paediatrician said "Either you teach her to sleep through the night now, or she will continue to wake up for food until she is about 2 years old" - i.e. stop the night feeds, when she wakes hug her kiss her etc but then put her down, repeat with short intervals until she goes back to sleep. Persevere the 2-3 terrible nights and then enjoy the full nights of sleep that follow.
We followed that advice and never looked back. Everybody here gets their baby to sleep through stopping night feeds before they are 6 months old. After that, apparently it gets harder.
I am surprised to see that in UK sleeping advice is often related to weaning or at least adding cereals to milk. Idea seems to be that babies wake at night because they need the food. I can't judge whether that has truth in it or not, only say that in our experience it was habit which was unlearned in several days.
It saddens me to see babies weaned early because parents think they will get more sleep, though...
