Kids go through developmental stage changes and when they do their sleep and eating patterns often change with the child. At two, this is very likely at least a part of what is going on.
Having said that, you did have a couple of things going on that might have been counter-productive to your child's sleep as well so even though they are no longer part of the equation, I'll mention them for future viewers:
Things to Get Rid of
- The TV is not your friend! Screen time right before sleep actually makes the sleep less deep. As Torben explains in a comment below, the light prevents the production of melatonin which helps in reaching a deeper sleep. Depending on the type of TV show being watched, it also is not necessarily calming either.
- Sugary Drinks or really anything other than water are generally a bad idea except during waking hours for a lot of reasons including dental health, nutritional health and deepness of sleep.
Things to Do
In addition to just knowing this may be a passing phase due to a developmental leap that either just occured or is about to, it may also be helpful to know that kids have to learn to self-sooth in order to return to sleep. This is easier for some kids than others, but having a regular routine helps kick the reaction in gear. It is very similar to how a basketball player will have a routine for free throws or a tennis star a routine for serves.
- Try to help your child with developing this by having a regular night
time routine at bedtime. The faster they get into that deeper sleep,
the less likely you are to have middle of the night wakings that get
them fully awake (after a little while of getting that internal clock
reset). If you have a routine for bedtime, you can help them figure
out a shortened version for falling back asleep. For example,
fluffing blankets and petting a stuffed animal at the very end of
your routine and just before sleep at bedtime might be repeatable for
a two year old in the middle of the night trying to get himself back
to sleep. This question on SE is very similar to yours but
focuses more on the bedtime aspect of sleep than the middle - of -
the night wakings. The answers offer a lot of input about how to go
about a bedtime routine that helps "prep" kids for sleepiness and you
may find some helpful hints in the answers to it.
There are times when no matter what you did at bedtime, kids will wake up and may have a hard time falling back to sleep on their own (even if they are good self-soothers). My daughter was the same way - sleep has always just been a tough thing for her. She sleeps well when snuggled up with me though. Here is what we did in regard to the developmental stuff and just helping her through it. Some kids just need a lot more reassurances in the night. We made the contrary to most decision to let her come in and just snuggle in our bed for a little while to help her body get rested and back into the habit of sleeping. Then we helped her transition back into staying in her own bed by:
- Setting her up with a nice big body pillow she could snuggle and hold
if she woke up.
- Providing her with a low-light night-light and glow in the dark stars on her cieling.
- Setting a rule about when she could come in and giving her a digital clock with a sign on top that showed what the clock would look like when she was allowed to come in. Since she often came in at about 1:00. We told her she had to wait till the clock said 2:00. This way, she wasn't made to feel like she just wasn't wanted all of a sudden - it was really about learning how to fall asleep on her own. When she was doing well and sleeping until close to two, we switched it and said 3:00. Then we moved it to 4:00, then 5:00 (wich is generally about when we start getting up anyway).
It worked really well for us. She felt supported and loved and got the cuddle, sleep and reassurances she needed, while we did too. She still had occasional spurts where we had to go through it all again (like at three, when she would wake up to go to the bathroom and couldn't get herself back to sleep, or when she was sick, or at five when she started schooling and her bedtime had changed) but it never takes very long to get our bed back - and each time she's needed a little sleep "work" how long it took to get back on track has gotten shorter.
