I want to find the age of the mother's youngest child.

If, for example, I have data as follows:

Mother ID:        Child ID:     Child Age:

1                         a                  1
1                         b                  2
1                         c                  3
1                         d                  4
2                         e                  10
2                         f                   10
2                         g                  12
3                         h                  5
3                         i                   7

Is there a simple command to tell me the youngest age for every Mother
ID or  do I have to use a do loop and if statement to do this?  If so
can anyone help me out with the most efficient way to code the do
loop.

I have used - collapse - and an if statement to count children under a
specified age before but I can't seem to find a command to do what I
want above.

Thanks ahead of time if you can help!

Ian
