How many bottles?

My son is almost 7 months old, he is a brilliant feeder I couldnt be more happy with how well he feeds. He is on 7 ounces per bottle.

Since he was 5 and a half months I gave been testing him with purees and baby yogurts. He has taken to food really well!

Today he woke up and had a bottle around 6 am. Then had another bottle at 11. But at 1pm he had a bowl of baby porridge. Then he didnt eat until about 5 which he then had small bowl of puree cream cottage pie then a small bowl of baby yoghurt. Hes now having his bedtime bottle at half 8 then off to bed!!

So thats only 3 bottles hes had today?? He seems full as he bursts out crying when he's hungry.

Is three bottles enough as I know he needs milk still for a long time yet?
