I was planning to make our niece a cute summer dress with matching bloomers that I will take when we go visit them in May. I bought a pattern like this:

I called SIL and she said her daughter was 30" long and 25lbs. at her 9 mo. appointment. It won't be warm for another few months so she will be a little over 1 yr. old when she can wear the dress.
Check out this (pdf of the pattern sizing).
Too small - right?
Re: help with kid's clothes sizing/pattern
yeah I think I can do that. I'm pretty good at sewing with out a pattern for myself. The kids sizing thing throws me off. I had no idea the precious little baby I met a few months ago got so big! haha.
