Breastfeeding is hard :(

It’s so hard. He’s 8 days old and I’m constantly worried if he’s eating enough. He’ll act like he is done eating but when I put him in his crib he’ll fuss and want to eat again. I can’t put him to sleep unless he’s been fed first, so when he doesn’t fall asleep it makes me feel like he isn’t getting enough. He has normal poops and pees. So at some point he’s getting enough. Sometimes he acts like he’s hungry but when i go to breastfeed him he will just sit there with the tip of my nipple in his mouth. I feel like such a failure. I feel like I’m not doing anything right. It’s so frustrating. Nights have been better. I love him so much and I don’t want to switch to formula, I don’t even know how much formula he would even need, but sometimes I feel like I can’t handle breastfeeding. I feel like such a crappy mom already 😭 I’m just so tired all the time, this first week has been so rough, I feel like I’m alone
