I have two kids now, and I think I'm doing a horrible job. I never won't. I wish I had a super confidant reply but I can't muster it here. Both of my kids had horrible colic, which meant for about 3 to 4 months of their lives, they just screamed inconsolably for 12 hours at a time and there was nothing anyone could do. We took them to the doctors, they did their thing... but having your baby scream in your face all the time kind of makes you feel like shit all the time. Silver lining: they DO grow out of it! Just watching them learn to smile and laugh and sit up makes all the sleeplessness and feeling like garbage really worth it. You'll never feel ready to have kids, never. Weirdly, it makes you more concerned for your own well being because it makes you remember all the fucked up things your parents did and makes you so terrified to hurt your own children in the same way by being careless, selfish or stupid. Damn... I hope I'm doing a good job, I just want my kids be be healthy, happy, functional people. If they can do that, then I'll be the most happy. You just can't rely too much on books or advice. You just do what works based on your kid, and go by what helps them to flourish and learn and grow, it won't always be what's suggested or easiest for you as a parent.
