We sent 3 formula bottles (breakfast, lunch, snack) at 11 months but transitioned down to 2 bottles soon thereafter, after having breastfed until about 10.5 months. Only 5 oz each, but our kid never took to large bottles. Also sent a small tupperware (you know the small square ones?) of food for breakfast and lunch, not particularly caring if the food was typical breakfast or lunch meals. For example, some had a few black beans, blueberries, pieces of muffin, pasta with pesto, meatballs, or mashed veggie options. The afternoon snack was a little fruit and/or yogurt. Ours went through a bit of a food rebellion around 12 months, during which we had to go back to mostly super soft food like yogurt, oatmeal and breads. Mine got in teeth really late, so yours may be able to do harder foods. We also sent a sippy cup of water, which they began to offer with lunch or snack food as a way to ensure he would drink it. We never had any issues but our provider said that some kids need a little longer practice time to encourage them to drink something other than formula or milk.
