DS finally sleeping through, does this mean he needs feeding more during the day?

Hi,

My DS is 4 months old today and for the past week or two has started sleeping through, going to sleep at 8 and waking up at 6/7. Before this he'd wake up every 3-4 hours for a bottle. He is currently on 5oz every 3 hours during the day, sometimes he will just drink 4 and sometimes he will be sick quite a bit. My health visitor suggested putting his bottles back down to 4oz but unless he occasionally (not very often) chooses to just drink 4 then 4oz won't satisfy him at all.

I'm taking him to get weighed on Friday, but I'm worried that now he is sleeping for around 11 hours without a bottle then he needs to be having more during the day?
He seems to be putting on weight fine to me, but I have friends with babies a lot younger drinking 4-5 oz every 3 hours too and im worried it's just not enough especially with the big gap at night time!

Any advice would be great, he's my first baby and I'm still finding my feet with this whole motherhood thing!

Thank you!

I think he'll let you know if he's hungry.

DD started sleeping through at 13 weeks and her feeds didn't change at all during the day, she stayed on 6oz every 3 hours but just stopped feeding at night. She carried on gaining weight and following her line perfectly :)
