Mom2nat, Jade is e&emum(bluerose). She seldom posts here now.
TT, poor thing. Can understand your frustration. RaeAnne also went through a phase of weird behaviour. She doesn't like the fan and refuse to let us switch on any fan. If the fan is on, she will switch it off. But she keeps waking up at night cos it's too warm. Tried the air con then next day she didn't want air con either. It was very frustrating for me cos end up she never nap/sleep well. Can wake up every half an hour, how can the adults rest? Thinking back, maybe it's because I said if the fan is on while her hair is still wet, she will catch a cold so she 'skipped' logic and think the fan is bad. Cos she hates us to dry her hair with a towel nor a hairdryer. Also, when the fan is on, she may have gotten cold at night and pee. So, she may have associated the fan with peeing at night, and getting wet and uncomfortable, then scolding from the adults.
There's one period, Raeanne also refuse to shower, keep saying wait, wait when me or the maid ask her to shower. I think she's asserting her independence and testing her boundaries. Then, one day, we asked her, do you want to shower in Mei Mei's bathtub? And she said yes. Maybe she didn't want to shower sitting/standing on the mat anymore, just wanted the novelty of showering in a bathtub and playing with water. So, after that, she's ok cos everyday can bring a different toy to swim in the water with her.
Maybe you can try making it into a game? Don't force him to shower but entice him to 'wash' his favourite toy or wash his own shirt in the kiddy bathtub. Let him take out the shirt he is wearing now, then let him add some shower gel into the water to wash his shirt properly. Sooner or later, he'll want to jump into the water himself, then you can shower him? Or let him shower himself with your help?
Now, she's gone through these 2 phases but still at her change 5 shirts a night phase. We are still trying to overcome this. -_-
