When does it get better

If we're just talking about sleep related issues, it will get better soon once you've established a clear routine and babies will generally become less fussy after 3 months. As the baby grows new issues will pop up though, but from my personal experience the first 3 months were the toughest and it got a bit easier eventually, but probably because I've gotten used to it. Get help from husband/helper/ parents/in laws if you can. You don't have to do it alone. All the best!
