At 7 months I was feeding my son solids twice a day... once in the morning, and once at dinner time... Then he had bottles for the rest of the day.
Now at 9 months he gets 3 meals and 2 snacks plus about 3 or 4 six oz bottles.
Usually 2-3 baby food meals and 4-5 bottles. Every baby is different though so you should ask his mom.
4times baby food. bottle 3 times during the day. 1 bottlefeeding during the night.
