Throughout their growing-up years, children go through different phases, different likes and dislikes. There's no definite length for these phases and it's different for every child. My boy is currently going through a 'must have air conditioner during bedtime' phase.
It started some time last month. I usually switch on the air conditioner (AC) when I put the kids to sleep. Both of them sleep with us in the same room. Once the boy has fallen asleep, I'll switch it off then sneak out of the room. I'm still waiting for the day when he can sleep on his own. Sometimes if he's not in deep sleep, he'll wake up immediately when he hears the 'beep' sound when I turn it off. Back then, I just need to reassure him that I'm still around and he'll fall asleep again without fuss. But recently, he can't sleep back if he sees that the AC is off. If I'm not in the room, he'd get up and cry. It's the really pitiful kind of cry, as though he's been cruelly tortured. All I have to do is to switch on the AC again, cover him with the blanket and ask him to sleep. Then I leave the room. He has no problem sleeping without me when he's blurry.
There was a few nights he woke up at 5+, asked me why the AC was turned off. I told him it's cold and ignored him. He didn't sleep back till about 2 hours later (of course, disturbing me every now and then). :-|
To avoid the drama, what I do now is to switch on the ioniser (on the AC unit) when he disturbs me in the middle of the night. He's fine with that, although it's not cold. I guess he just wants the buttons on the AC unit lighted up. I doubt he's afraid of the dark as I leave the bathroom light on when they sleep.
Now that he can't live without the AC, I've got a very good 'weapon' during bedtime. If he makes noise/talk, I point the remote control at the AC and he'd keep quiet. If he plays with jie jie or moves around, I just point the remote and he'd behave. Seriously, like magic! hahaha But of course, he'd forget the threat after awhile. So got to threaten him a few times before he finally fell asleep. Sigh... when will this phase be over? One thing for sure, the electricity bill will be higher during this period.
