I fed at something roughly like 7am, 11am , 4pm, 7pm
I remember reading others were giving a milk fed prior to the nap, so bringing the milk early but in our case I don't think it was needed.
I found that with the solids coming between the milk feeds he would manage longer between milk feeds.
I did solids an hour after milk feeds so roughly 8am, 12pm and 5pm.
I didn't introduce snacks at that age but we were on 3 meals very quickly which not all LOs that age are on.
