F.W.
As a former sleep-deprived mom, who vows never to go there again, I hope I can help. First, does your son know this is a problem for you? You have to tell him that he needs to sleep through the night, and if he wakes up, give him things to do on his own, without waking you,to help him fall back to sleep...a special blankey or stuffed toy, that is a substitute for you, so when you aren't with him, your toy is still with him. Do not expect this to work the first few nights, but you have to be firm when he wakes you up, what he needs to do with it. Start a reward chart, if he doesn't wake you 5 days in a row, he gets something. Think of this as changing any other undesired behavior. Plan B, expect some tears. Change is hard on little ones. Plan C,, put a sleeping bag under your bed, and tell him that if he can't fall back asleep that he can come pull out the sleeping bag and sleep on the floor, but he cannot wake mommy or daddy. Kids sleep patterns change for no tangible reason, and then they change again, but it sounds like he has developed a behavior pattern. Lastly, you didn't mention that he is a snorer or not, so I assume that he isn't, but if he is, you need to think about sleep apnea, and him waking himself up. If that is the case, go to an EENT Dr. before you do the other suggestions. I hope this helps.
