Ok, I dug up his charts. Here they are:

For Actual age(10 months) he is:
3rd percentile for Weight
5th percentile for height
25th percentile for head circumference

For corrected age(7.5 months) he is:
25th percentile for weight
25th percentile for height
50th percentile for head circumference
He is dead on the lines with these!

Here's his growth since birth:
(Weight, height and Head Circumference)
Birth: 1545gms 40.5cms 28.5cms
1 month: 1905gms 43.5cms
6 weeks: 2190gms 32.5cms
2 months: 2730gms 47cms
10 weeks: 2925gms 48.3cms 35.2cms
3 months: 3480gms 50cms
4 months: 4260gms 52.5cms
6 months: 5560gms 58.5cms
7 months: 6295gms
8 months: 7160gms 65cms
9 months: 7720gms 66cms 44cms
10 months: 8220gms 68cms 45cms

I seem to have misplaced his 5 months check, but I remember he didnt put much on between the 4-5 month mark. It was only about 100gms for the month, at 5 months he went onto full formula feeds and thrived from then
