Breast feeding is a full time job I really want to give up already 😢

Moms! My baby's bottom is just so torn up and hot:( this rash won't go away fast enough! It hurts him so bad when he screams he throws up multiple times while getting changed! I don't know how to help him quick enough! Help!😭😭

So, does anyone else’s baby spit up a lot ? I feel like he just eats to much/to fast . I switched his formula to the sensitive kind , but he only formula feeds before bed and when we’re out . And we’re not out a lot . But he spits up my breast milk too. I’ll feed him and he’ll scream like he’s still hungry so I’ll feed him more until he seems like he’s not but he ALWAYS spits up. Idk what to do . I’ve tried burping more often , switching my diet , everything .

Okay, I cant take seeing my baby like this anymore . What saved your life helping a baby with a milk allergy and acid reflux ? He’s on nutramigen and it’s helped with his spit up not being clumpy and rotten but the spit up is still so much and 4-5 times every feeding . I’ve tried 2 medicines . Multiple formulas . He screams the second he stops feeding until he burps and it all comes out . I dont know what else to do for him 😭😭
