Baby feeding help

Anna

I need some help or reassurance... my baby is 9 weeks old. He got his imunisations 3 days ago now he constantly wants to eat. And he is up to about 6 to 7 oz. 2 to 3 hrs. He used to eat 4oz every 3to4 hrs now I think is to much. He cries and only wants to fall asleep by me or he needs to rocked. But I'm only concerned about his feeding. I'm always scared to overfeed but he won't calm down or take his passi. He is a big baby 13lbs at 9 weeks. Any comments would help ☺ thanks
