Brining back a night feed may help, I'd suggest a dreamfeed when you go to bed.
It is not unusual during early weaning (up to about 9 months) for nights to be disturbed when baby was previously sleeping through. This is often in the form of an early-morning-but-still-nighttime-really wake up.
Early weaning foods are often low calorie (fruit, veg) and baby may not have the wide range of food groups and the portion sizes of an older child yet.. Therefore belly gets full on lower calories and so milk intake can actually increase in the early weaning (6-9m) stage, not decrease as some may expect.
Babies can also start to feel dehydration during early weaning. Think about the amount of water/fluids baby was getting from milk just before you started weaning and compare to now. Is baby getting enough fluids through the daytime?
So, despite my waffling, I would recommend bringing back (just temporarily, don't worry!) a night feed when you go to bed. Because I didn't have a problem settling mine, I'd try for fully waking baby up for this feed - nappy change and the lot. Make it a bit like a re-set button at 10/11pm. So that once settled back to sleep after that feed, with a new nappy, it is like re-starting the nights sleep.
Also make sure baby is still getting plenty of milk feeds through the daytime to maintain calorie intake. I recall early weaning feeling like going back to the newborn days of spending all my time during the day either feeding baby or getting her to sleep - what with fitting in 3 proper meals, four or five full milk feeds, drinks from a beaker and all the normal daytime naps. Relentless feeing/sleeping marathon!
It does settle down though. I would then test the water after a couple of weeks. Skip the dreamfeed and see what happens. If baby goes back to early waking then carry on for a few more weeks with the deamfeed. If baby sleeps later don't bother.
We had a mix-and-match time for a while whereby if I wasn't knackered when I went to bed I'd give baby a feed, but if I was knackered I wouldn't give the feed but would expect an early morning. The dreamfeed need not be set in stone, its not an 'always' or 'never' thing. But does help on the times you'd rather not have a stupid oclock wake up call.
