DS4 is 9months, 3 weeks, can say Mammy/Mama, Daddy/Dada (at correct person), "Oh NO/ no" (when upset/sore), cuddle, ticktick (tickle), tick (clock), nose (while grabbing mine), triangle (knows simple shapes), Ada (for Adam, brother), so about 9 words. 4 really clearly.
Knows names of a few people, and himself (will look at correct one in response to "Where's X"), and a few things such as mirror, water, bath, nappy.
Claps hands when asked, or when happy. Does not crawl (does bottom shuffle a bit), pull him self up, or sit himself up, or walk or eat on his own....
There is a massive range of normal with all these things - some can walk at 7 months, some at 2years. Some are talking in sentences at 12 months, some at 3 years.
