Rachel sometimes use diapers at night, depends if I wanna wake her or not. Will sometimes wake up in the middle of the night and say vv. But I prefer to use to avoid a whole mess and clean up if she vv on the bed.
Congratulations!! Ming Cheuk will use less and less diapers.
But toddlers at this age are unstable in their vv performance. Rachel will 失手 too, mostly in school. Maybe she just raised her hands up too late, and did not get attention immediately...... oh well!
