FTM💕 please help❤️

My baby boy had his 1 month visit yesterday and the doctor said he’s doing great. But she was a little concerned about him eating to much. He was eating about 3.5-4 oz per feeding. She wanted him to start eating only 2-3 oz.

So my question is do I start only pumping up to 3 oz? Or do I pump for 20 mins? Or what?

Another question..

I also started to have him to latch on, but he doesn’t stay on it for long. He’ll stay on one breast for about 10mins. Is that good? Is he getting enough milk? If he’s still fussy to I give him the bottle? How many oz?
