Restless sleep

Last few nights have been tumultuous, Dominic has not slept very well. He goes down easily enough, but at about 2am and starting from there, he'd toss and turn. He also makes frustrated noises like "Argh. Argh. Argh." repeatedly to express his unhappiness. I'm not sure what he wants because he can't tell or respond to me. After a while he'd settle down, but sometimes this would go on for some time.

Last night he kept up the wakefulness for some time. It was sad to see him so irritated and yet unable to help. Finally he settled down after a bottle of milk. Because of the poor sleep, he woke late today.

I find that when Dominic is overstimulated during the day, it would manifest at night and he'd have restless sleep. Also, he may be going through a growth spurt or a renewed love affair with milk because he is drinking more these few days. Just a week or so ago I thought we had cut off the middlle-of-night milk feeds, but judging from his sleep lately, I think I have to give him milk once again. It's difficult to know if he is really hungry or just wants to drink out of habit. But since he eats less rice on the weekend, he may really be hungry at night.

I think another reason why he is so restless at night could be because his brain is forming links from what he as learnt and probably has lingering irritating or unresolved issues from the day. It is part of growing up, I guess.

Another point of worry is his ear wax - there's plenty of it in both ears! I'm worried the accumulation may affect his hearing. Is there something to use for a non-invasive ear cleaning??
