Mommies, what time does your child go to bed? My 1.2 will be 18th, but it doesn't walk, takes two steps and cries, starts crawling immediately. Stands well without support on smooth surfaces and on the bed. Doesn't want to take the second handle either. Not put in a walker. Crawls and walks well with support. I know that it's normal until about 1.6. When should I sound the alarm? And why?
