Hiya,
My bub is around the same age (5.5mths) & was alot like your bub. was doing 1 night feed/NW then went to 2-3 NWs.
I would feed at each. but sometimes he would wake after 5-6hrs from bedtime & not feed 'good' & then wake a few hours later & not feed good either. then have average to ok feeds during the day & they were 3hrly OR he would go 4.5hrs if we were out & about.
After talking to friends & ready a few books & websites, I realised that because he was feeding a few times at night he wasnt as hungry during the day so kinda snack feed, so my bub was stuck in a cycle of getting his feeds over the 24hrs rather then the ideal 12hr daytime. I realised the only way to break that cycle was to start weaning the night feeds & stretching out his day feeds to 3.5-4hourly so that he was hungry enough to get a goooooddd feed in.
I went with a gentle approach to weaning

& we've made some great progress!! has taken nearly a week BUT it wasnt very stressful or time consuming & very little tears thank goodness.
He is now feeding every 3.5-4hrly having 3 breastfeeds then a bottle before bed (4 feeds) plus solids 3 times a day.
Let me know if you would like to know what I did for the weaning. but here is our routine give or take 30min either side of the times:
E- 6.30am both sides
A-
E- 7.30 breaky
A-
S- 8.30ish, depends if he's been awake from 5ish or if he's woken & gone back to sleep. (sleep is 1-1.5hr)
E- 10.30am both sides
A-
E- 11.30 lunch
A-
E- top up from one breast
S- 12 (1.5-2hr)
E- 2-2.30 both sides
A
E- 4-4.15ish top up from one breast or 100ml bottle (I do this because an hour later he has his dinner)
S- 4.30ish catnap
E- 5-5.15 Dinner
A- @ 6pm bath etc
E- 6.30 220ml bottle
S- 7pm bedtime.
He could probably do with a longer A time to get longer naps BUT because we have a kindy run this works for us until he's ready to drop the evening catnap where we'll push out that last nap. its hard with kindy run as the longest that lastnap can go to is 2.30pm.
Hope this can help you in some way?? its so hard when they take a backwards step. wish Id gotten on to it sooner.
good luck
