Oldest walked at 12 months and "talked" with baby signs at 9 months. Words at 12 months and full sentences at 14 months. He is hearing impaired but is very articulate- he got a 150 on the WISC verbal at age 6. He talked very fluently, big words, long sentences at 16 months.
Youngest walked at 10 months and talked full sentences at 12-14 months. He does everything earlier, I guess b/c he's trying to keep up with big brother, LOL!
