Ok, I see, sorry not sure why I thought you were bottle feeding. Extra solids to help baby STTN is an old wives tale that is just plain wrong most of the time. It helps a small proportion of babies but when they're reducing their milk intake to accommodate solids, they still need the calories from milk some time and they take it at night. Its still within the realms of normal to have one night feed at this age, but really, I think its reasonable to not want to feed 3 times a night and also a reasonable expectation of baby to not need 3 feeds in the night.
I would probably cut back a bit on the solids and put milk in their place. Something like this:
7 - WU, milk
8/8:30 - breakfast
10:15 - nap
11:45 - WU, milk
1ish - lunch
2:45 - nap
4:15/4:30 - WU, milk
5:30 - small dinner
7 - BT BF
clean teeth, etc.
7:30 - asleep in bed for the night
Another way to sneak in calories during the day is to give EBM or formula in a cup/bottle with meals rather than water - made a world of difference for my DS at around this age.
