Hello My Son Is 6 Months Old And Is 9

Hello
My son is 6 months old and is 9 kgs.
He was 3.75 kgs at birth.
I started semi solids once a day at 4 months and twice a day at 5 months as he was quite hungry.
Now at six months he eats semi solids 3 times a day and 60 ml formula two times a day.
Breastfeeding continues to around 5-7 times a day.

Is this too much diet for him?
His growth curve showed that he was slightly overweight.
I feel that he is hungry so i feed him as above.
Kindly suggest if changes are needed .
Regards
SB
