已经晚上吾比佢饮太多水,吾识起身去VV,已经每晚用小童diaper, but his VV now is too "big" even kid's diaper cannot hold that much, always (maybe 2 - 3 times per month) make the bed sheet and quilt wet!!!! I try to wake him up to VV every night around 3 to 4am, but sometimes I also fail to get up (too sleepy). Do I need to take him to see doctor?? Is it a bit abnormal for a 6-year-old boy like this??
