Some adopted kids (but not all) come home to their forever families with issues. Some have sensory issues or problems with textures. Some have hoarding problems or other issues with food: eating too much or not enough. Still others have issues with strangers or feeling distrustful of one gender or another. Yet others have issues with forming loving bonds and attachment to their new family. All of these can mostly, if not entirely, be battles that the parents and child can fight together during the long patience of daytime. If they are lucky, the parents may even be able to enlist the help of other soldiers like immediate family members, grandparents, doctors, or therapists, to help fight the battles.
However, this is not true for parents with children who are battling the demons of sleep issues. When your child has a sleep issue, you don't have the luxury of summoning up patience and love while you are at your best, but instead, you have to find the compassion and serenity (often multiple times) in the dead of night. When people vaguely say "let me know if there is anything I can do to help" you can't say "come on over tomorrow about 4 am because that is when my child is going to wake up inconsolable and screaming, and you can deal with it while I get to sleep through it." No, these are battles that are intimately fought solo, with only Erebus to keep you company.
The way that sleep problems manifest in the night might vary, from quiet, sleepy whimpers that only need a soft touch and comforting whisper to guide the child back into sleep to full blown meltdowns, characterized by quick, deafening, staccato screams and wild, stiff movements, sure indications that his amygdalae were working overtime again, and your poor little kiddo now has so much cortisol coursing through his veins that it will be impossible for either one of you to go back to sleep; get ready for the sunrise because you are now Up For The Day.
For the parent of kids with sleep issues, knowing that when you lie down for the night, intending to power off and recharge like the device plugged in beside your bed, but aware that you never really get to do so, you never actually get into a deep and restful slumber. Instead, you are still on alert, never quite shut down, never quite recharging.
The problem is compounded when your child with sleep problems also doesn't seem to need more than 9 hours of sleep daily, and is still needing and taking a short daytime nap and therefore only getting a little more than 8 hours of rest during the night. This means that parents who are already stressed-out and sleep deprived have zero time to enjoy a book, have a hobby, watch a movie, catch up on a TV show, or talk about life and decompress over a glass of wine in the evening but instead must send themselves off to bed minutes after the child falls asleep; it is the only way to minimize the zombie effects of spending part of the night awake to comfort a child followed by a 4 - something - o'clock wake up call that is gauran-damn-teed to happen in 8 hours.
Imagine waking with your child 8 times between 8 pm and 4 am, and then a full-blown meltdown happens. There the two of you are, at a time when only people catching an early flight and night shift nurses are awake. Your child, in fight-or-flight mode, short punctuated screams emanating from his little body, not wanting comfort or anything you can provide, and you, roused once again from sleep, at first groggy and then your own amygdalae kick into action. Your spouse trades places with you so that you can go back to sleep. But you can't because your child already put you on high-alert and even though you are sleep deprived, you can't help but do the sleep math in your head, "Even if I fall asleep right now, I'll still only have x hours of sleep before I need to slog off to work..." You even crawl in bed next to your daughter, hoping that her soft rhythmic snoring and warm bed will pull you into their orbit, inviting you back to sleep, but instead, you sob (albeit silently) into a pillow next to her, (simultaneously envious of the 10-11 hours of sleep she is getting and relieved that one of your children is sleeping soundly) because you are exhausted and because no one but your spouse can understand just how exhausted this is and because you cannot see an end to this madness and it is such an emotionally debilitating and lonely job.
