Hi,
Anyone who says there are no such kids are lucky indeed. I have three kids and only ONE like this.
I ended up "Attachment Parenting" with our 1st son - and only learned it had a name later as well. He simply did not sleep and refused almost all food but breastmilk, so the ONLY way I could get any sleep was to co-sleep and night-nurse (I am the working parent in my family). There were days that I walked around seeing "faerie lights" I was so exhaused. I "wore" him as much as possible because it was a good thing for all of us, since I was at work all day. He was so tiny that I was able to carry him a LONG time, even though I am 5'1" on a good day.
We discovered later that he had a medical condition that meant he didn't really need to eat or sleep much, since he wasn't growing much. He is 6 now, we are treating the condition, and he usually eats and sleeps like a champ. BUT that probably doesn't help you as I am sure kids can be high-need without any medical issues. All I can do is assure you that it will pass.
My son weaned quite willingly at age 2.5. I had been singing to him as I nursed him and we transitioned to singing only. I sang the same song every night.
We could probably have moved away from co-sleeping then too if we'd had anywhere else for him to sleep, but we didn't and so we co-slept for awhile longer. A lot longer, actually. If you don't want to co-sleep until he's 5 or so, you should have a window between ages 2 and 3 when you can transition her to her own "special" bed and then out of the room.
Son #1 was 4 or 5 before he could sleep through the night, but by age 2, I was usually only up with him ONLY once a night. Not getting up would not have been an option - we would have had to strap him down to keep him down once HE decided he was getting up. SO better to get up and calm him. But really, after the previous 24 months, this was no big deal.
As hard as things are now, keep in mind that as your child gets older, having a LOT of energy and a powerful will can be a good thing. Hang in there and do your best. And get as many SOLO naps as your life will allow.
And when you have another child, rest assured that odds are that child #2 will not be exactly the same and you'll be well-trained regardless! We did a lot of the same things with son #2, because he was adopted and many of these things are recommended for adopted children as they (and we) may need help attaching.
We have a pretty unusual arrangement at our house as far as sleeping goes now, and probably will for the next 2 years. People used to hassle us and we'd just ask if they were having difficulties with our children that they needed to discuss with us. The answer was always "no" and the hassle has evaporated over the years.
Do be prepared when preschool starts that you may have to add some things to your home that are usually for "special needs" kids. We have a "safe space" from Kodo Kids which was HIGHLY recommended for son #1 by his preschool teacher (it's usually used for kids with sensory issues, which our son does not have). I asked that teacher if he seemed more emotional than other kids and she said "Oh, yeh." But like us, it wasn't something she thought should be changed - we just need to teach him to manage it. It will be a lifelong lesson for him. He is VERY bright and a wonderful kid - he just has HUGE emotions, LOTS of energy, and a powerful will. But rest assured that, as a child ages, this IS something he or she can learn to manage. We all have our "stuff" anyway.
Son #2 has hella tantrums (something he came to us with) and we've found that putting him in the "safe space" calms him quicker. Good luck and hang in there. It gets easier!!!!
