Straight up those people who tell you don't worry sleep will return, oh the crying will stop, the feeding will get easier and so on and so on, are lying to you!
Yes the crying will stop, then it will be whining and talking back then silence and lying. The feedings may get easier for a while then the fighting over dinner will start up again. The sleep, well let be honest mothers we will never sleep amazing ever again. We hear everything, we pretty much sleep with one eye open. So sorry but just kiss sleeping goodbye, you will learn to adjust and if you don't like coffee you will. I know that part first hand haha.
That being said it is amazing! being a mom is truly the best thing you have ever done. Don't be scared, don't second guess yourself, don't let other people tell you what to do. You know your kid the best, go with your gut it is usually always right and if you don't ask for advise and someone gives you some just say thanks but I got this.
Enjoy every sleepless night, every tear drop, every messy face, all the bumps and bruises; because it does go by fast. Every age is fun in its own way, it is also challenging in its own way so have fun!
Proverbs 22:6 says "Train up a child in the way he should go; even when he is old he will not depart from it."
