Sleeping baby

Melissa • 26. I love my husband and so thankful for my friends & family. We're expecting our first little one.
My little girl is almost 3 weeks old. At the moment she only sleeps, poops and eats :) which is normal and so cute, I just want to know when babies start staying awake between feeds? I'm not sure when babies become more awake and want to play or if they have winds and are awake because they need to be burped. Any advice?
