I mean non stop sleeping, without waking up once.

Yeah, babies can be nerve wracking when they can't manage to do something as basic as sleeping, or getting themselves to sleep. I feel your pain.
It varies even by child though, so there are no hard & fast rules.
There are legends of the "angel baby" who don't stress out the parents in this way (i.e., making you pull your hair out wondering how to get them to sleep), even as babies. But I never got one of those :)

I remember one of my girls would take her naps in a playpen in my office. She would go to sleep, as long as I put her down for her nap, and stuck around. I queued up a certain soundtrack, Final Fantasy III, and took out the too-exciting tracks that were "inverse lullabies" -- tracks that would wake you up. I called that folder "[daughter's name] Sleeping"
We still listen to that particular folder of music. She turned out to be super musical and a gifted vocalist.

As an aside, there is certainly a natural role for fathers when it comes to discipline. I feel bad for any families with young children without a father. There are so many times we're 100% good as long as I'm around to so much as utter a command (nevermind raising my voice) -- there's something about "daddy", that deep voice with strength and authority behind it, that is automatically scary -- and extremely necessary when you need a good dose of authority/fear to motivate. When the kids get hurt or sick, they need mommy like nobody's business. But when you need to keep them in line -- sometimes only daddy will do.

Need I point out the necessary link between God, authority, and fatherhood. The father stands in for God in a family, and gives kids an idea or conception of what God (Who is invisible) is like. Kids with a messed up concept of "father" ALWAYS end up with a messed up concept of God. That goes for love, mercy, wisdom, power, fairness, etc. Fathers have a grave responsibility to do a good job here! If you're whipping your kids left and right, always stern and severe, impatient, a real S.O.B. -- your children will certainly think God is a (nevermind). But if he's absent, or virtually absent, then kids will have a hard time believing that God loves them or takes an interest in them. But if you spoil your kids, be over-permissive, then kids will grow up to think God would never punish them for anything, especially for breaking silly "rules".

But back to the topic --
I think dads are more impatient about this, and even less equipped to deal with babies-refusing-to-sleep than mothers are. Broadly speaking, women are more patient with children in general. Not to say that limits can't be reached, at least on some days.

I coslept with my toddler until she was a year and a half. I also was breastfeeding her during that time. During that time, I would sleep beside her in her playpen (floor bed) and wait until she fell asleep, and sneak away. She's 2 (she's weaned) and I still do it. If she cries in the middle of the night and she's really upset, she sleeps on our bed or one of us will sleep with her, but for the most part she sleeps throughout the night. 

Ours is almost 2, she’s still nursing, sleeping on the bed with mom. Ditched the crib months ago and it has been one of the best things we’ve discovered. 

I wonder if it has something to do with not getting enough food throughout the day and at night? We’ve been really trying to make her eat as much as possible but she’s very picky and refuses to eat enough protein. She mostly like berries and stuff that isn’t protein. 

We do try to give her as much yogurt and stuff like that that is more filling.

Lately she’s been waking up like within an hour after she falls asleep at night. She wakes up crying, she’s nursed back to sleep, sometimes it can take more than an hour. She’ll wake up 1-2 times more after that and then several times after midnight as well, each time to nurse. 

Does she nurse to sleep? If so, try to break that habit (which may require bringing back the crib). You think she's waking up to feed but in fact she just might be waking up, and since she has a nursing-sleep association, she cries to nurse so she can go back to sleep.

For your consideration. Have dealt with this with several of ours and learned the hard way.

How do they fall asleep without nursing?
