Deb,
If your lo is about 10/11 months old, he still needs to have a minimum of 20oz babymilk until he's at least 12 months old, the milk has the greater proportion of the nutrients babies need for healthy growth and development rather than the solid foods, and altho they need both milk and solids, and their milk intake will gradually decrease, it shouldn't drop below 20oz!
I have a different routine to Taygenmom which uses milk as a snack between meals, offering water with the meal, like this (dd is 14.5 months):
5.30am bf (nap)
7.30am solid breakfast & water
10.30am milk
11am nap
12.30pm solid lunch & water
3pm milk
4.30pm solid tea & water
6.30pm bf (bed)
She always eats more at breakfast and tea than lunch, and her appetite varies day to day depending on tiredness, distraction, teething, illness etc. She has been introduced to solids using a baby-led weaning approach so we don't spoon feed her, so if the spoon is a problem, could you increase the amount of finger foods you offer instead, and again accept his refusal if he indicates he's finished?
You could also teach the sign for finished if you'd rather he 'told' you than simply discarding what is on his tray!
