CHILD DEVELOPMENT

I'm scanning the Internet for articles on child development. I know as a mother of 3 I shouldn't need to but Léon is definitely not following the normal expected pattern: both Marcel and Charlotte learned to sit first, at 7 and 6 months respectively, then to crawl at 10 and 9 months, they said their first intelligible word at 11 months, then to stand around 12 months and finally to walk at 14 months.

Yesterday Léon was 8 months old. He's been standing since he was 4 months old, and is crawling backwards now, and has been since 7 months but he won't bend in the middle and refuses point blank to even attempt to sit. Watch this space to see if he is the first kid to walk before he can sit! Do I have another potentially stubborn little Charlotte on my hands, I wonder?
