I'm on day 2 after birth an I've been breast feeding maybe 15/20 mins a breast during each feeding but my lil monk still be fussy an crying afterwards so I give him maybe 2oz of formula an he drinks it down like he hasn't ate. I'm still at the hospital until tomorrow due to my pressure the doctors nurses an lactation lady say I'm producing enough an later on more is going to come. But I feel like I'm starving him so I give him a mixture if breast an formula but I just want to give him my breast any suggestions on producing more milk or something anything will help an my breast don't leak I just feel like he's sucking out nothing you know.
