11 week old waking every two hours

Cindy
Hi, I'm a new mom and I'm having trouble with my baby's night sleep. She would wake up every two hours maximum four (happened only once). I've read articles that baby starts to sleep longer stretches at night but she still wakes up every two hour. What I do is every time she wakes up, I assume that she's hungry so I've been feeding her every waking. And she wants to be held all the time, can't put her down to her crib until she's deep sleep. Should I continue doing what I'm doing until she's older and see her progression or should I start sleep training?
