Hi D. - I am so sorry you are having to endure this frustration. I can completely empathize with you. My child had severe sleep issues until about 15 months. He's now almost 27 mths & is pretty much a typical 2-yr old.
One of the things I've learned in the process is that most kids have sleep issues of one kind or another. There are basic things we should expect from them, but there will be seasons in their little lives where sleep problems crop up & it's our job to help them get back to the "normal" for them.
Has your little one ever been able to fall asleep at night? If so, try & think back to what was working at that time. Are there things that have changed? Bad habits that are now hindering him to sleep?
Of course there are plenty of books to read, but as we all know, when you're pregnant & you have a little one to take care of, reading is one of the last things you have the time or energy to do!! SO - here's what I learned from the multitude of books I poured over during the first year of my little guy's life:
- CONSISTENCY: this is absolutely crucial to have success in your strategy to get your little back on a normal sleep schedule. If dad is available, be sure to include him 100% in the plan & both need to commit to being consistent. I can almost guarantee you that no matter what plan you implement, you will see success in, at most, 2 weeks time.
- STRATEGY: put some serious thought into what you want your family to look like in regards to schedules. By now you know if your kid is naturally an early riser, or he's a light sleeper, or his habits. For us, our boy only needs 10 hrs of sleep on a typical night. So, it would be foolish to put an expectation on my child to sleep 12 hrs a night. I can put him to bed whenever fits us best, but I know he'll only sleep 10 hrs tops. When my son was 7 mths, he was falling asleep at 10PM. Obviously wasn't working. I implemented Ferber's cry-it-out method (which really wasn't that rough at all), & in 3 nights he was falling asleep at 7PM. Now, he's in bed by 7:30PM, & asleep by 8PM. It never would have worked had I not stuck to my guns. When he's been sick, the schedule gets thrown out of whack. I give him grace for a week or two, & if he doesn't fall back into his normal schedule, then we make a plan & in 2 or 3 nights, he's back to normal. Sometimes it calls for me to be in his room for an hour or two just putting him back in his bed when he tries to get out. He may be mad, crying, yelling, but it's never been more than 1 or 2 nights that I have to do that & he understands that he's to sleep in his own bed when we say so.
- SLEEPING LOCATION: By now, your child needs to be sleeping in his own room, in his own bed / crib. It is not expecting too much of him to do this. It's still just a matter of being consistent in the expectation, which we all know can be difficult when it's 2AM & everyone just wants sleep. Since you're in the later stages of pregnancy, it will probably be easier to have dad step in & make sure this happens as it may take awhile for a few nights.
If you have any questions or want / need more suggestions, don't hesitate to email! The thing I kept in mind over & over was that it is healthy & better for my child as well as the rest of the family to get him in a good sleep routine. Good luck!!
