Used to breaki WU bottle then solids hour later, snack around 10am then lunch 11.15/11.30 depending on sleep then nap then milk 2pm ish then solids 5pm ish bottle at BT mine gave up afternoon bottle about 10/11 months but he loved solids and just had 8oz WU and BT bottles. I just went by him really and after a week of not being too fussed at afternoon bottle I just swapped for a snack.
Like u say when your on 1 nap it makes the day easier to fit stuff in and we sometimes did half lunch before nap at 11am then half after at say 1.30 ish.
