In the past week or so, Sexy has been very bad-tempered - throwing things when he is unhappy, get into very bad mood on very little things, very sensitive (we might not be talking about him, but anything remotely negative, he will throw a tantrum), hitting people and got very possessive and refused to share. I have tried it the soft way (to explain to him) and hard ways (罰企) but both seems useless. It doesn't help too that he is very stubborn (he was 罰企 for nearly an hour yesterday, but still he refused to apologise). I also tried the reward system to suggest to Helen (which I have used previously) but doesn't seem to work. The only thing I can boiled down to is that both my husband and I have been quite busy, but I have tried to spend at least an hour with him every night before he goes to bed.
