What age do babies...

• start holding there own bottle?
• start talking??
• begin potty training?
• start crawling??
• start walking?

1) around 6 months or so
2) different for every child... some start at about 10 months, others decide to wait much longer
3) Around 2 years of age (that is just an average)
4) Around 6 - 8 months
5) Around 1 year

These are all averages as EVERY baby is different and grows at their own pace.

"What to Expect: the first year": excellent book

Amazon.com: What to Expect the First Year: Books: Arlene Eisenberg

All babes are different. Walking average is a year. Potty training from a year and a half to 2 years. Crawling about 6mths or so. Bottle holding starts about 4-6mths. Talking REALLY differs... depends on what you mean by talking. Fluently about 2 1/2 years. Saying dada about 6mths or so. My daughter did everything "early" by most website's "average" so I tried to put up their "averages"
