My 1st-ever Self-only HDHP coverage was effective starting April 1st, 2010. In September 2010 my daughter was born and first full-month of Family-Coverage was October 2010.

What is the Maximum allowed contribution towards my HSA for 2010? Using Last-month rule, can I contribute max $6150 allowed under Family-Coverage if I'm OK with testing period?

I plan on staying an eligible HDHP member during the entire testing period (Upto Dec 31,2011).

Thanks in advance.
