DS keeps trembling, in a happy way. He's at that stage where he likes to sit and examine a toy for minutes on end. This week he has started having spells of trembling all over while he does this.
It's definitely not fitting. More the kind of fatigued muscle trembling that I would do if I tried to lift DH. He seems to get so overwhelmed by his interest in something that he tenses up all over and shivers for about 10 seconds at a time.
It doesn't bother him at all, just a little odd! DD never did this, so hoping to hear that some babies do.
