Some babies crawl as early as 4 months, most can crawl with their tummies full off the ground by 10 months BUT many never crawl at all.
Talking doesn't happen until 14 to 18 months and then it's just a few words. By 8 months, most can say mama and/or dada but not to the correct person. By 11 months, most use them for the right person. By 13 months, most use 2 additional words. By 18 months doctors like to see 10 to 20 words. By 24 months, doctors are looking for 2 word phrases. By 30 months most can use 4 to 5 word sentences. By 36 months, most can hold short conversations. Keep in mind that pronunciation lags WAY behind this. Most kids are still learning to say some sounds correctly at 5 years old.
if you are concerned, talk to your doctor and get an evaluation.
