Self Potty-Trained

My boy was potty trained by my mum when he was three months old. He would alert my mum when he needs to pass urine. However, this only lasted for a short while. After he was under the care of my MIL, he was pampered and he was subsequently reluctant to even sit in a potty. It took months for my maid to get him back on track. Last month, he still pee in the cloth diaper. To our surprise, he has a TOTAL change past 2 days where he requested us to bring him to toilet to pee right before he sleeps and more interestingly, he wake-up middle of the night yesterday when he asked us to bring him to toilet. :P What a surprise! After waking-up two rounds to make milk for two babies, I refused to wake-up again. I called my husband to settle it. My husband was initially requested him to pee in the diaper but I told him to better bring him to toilet. My boy was so excited when his father finally dragged himself up. Then, we start to worry how to finish our stock of over-size diaper.
