11mo - is this enough food?

[NewChoos]

Have posted before, remain a little concerned re DS's weight and intake.
So....
0630 BF
0730 Bfast: cereal made with formula - approx 2 tbsp, small piece of Melon
0900: BF before nap
1030: formula 120mls
1200:2-3 tbsp spag bol. cracker and cucumber, refused dessert
1400: BF before nap
1500: formula 120mls & oat cookie
1700:1 1/2 tbsp cheesy broccoli mash, 2 pots fromage frais, strawberry and a cracker
1900 will have BF

Does this seem enough? On work days he takes between 300-500mls of formula and has a bf in the am and before bed.

Its not a huge amount but if its any consolation my DD was much the same (probably eating less than this as often meals refused) at 10-11 months but really got into food around 12-13 months (a month or two after starting walking). She's small (9th centile) but has been on this curve since about 6 weeks of age so I am not worried (she was bigger at birth). She's still not a big eater compared with other babies her age but I no longer wonder how she is surviving!
