Completely. Bubs is still getting used to feeding. A full belly = a sleepy baby. And sleep promotes sleep.
Is bubs only doing this when you have woken her? She may not be hungry, thus leading to the stuffing around.
My DD from the day of birth, sleeps at least 6-7 hrs a night. Middies told me to wake her as well but then others said leave her when she's hungry she scream for it.
Yes, it's mainly when I have woken her. The MW and health nurses all said don't let her go over 5 hours without a feed so if she sleeps good I have to wake her maybe I'll let her go next time. Will anything happen?

I have been feeding from one side then doing a nappy change and burp, then feeding the other side. It's always the second side that she fluffs around on.
