I found Carole Barenys' pattern long ago, back when I followed the knitting.about.com site. I really liked that site. They had lists and links to online patterns.
I've done this sweater at least three times before, so I'm calling this No. 4. It is a gift. It is a fun knit.
The yarn is Adriafil Knitcol; advertised as worsted but I would call it sportweight! I got 6 stitches per inch. Nevertheless, I like the yarn, warm, soft enough for a baby, and machine washable.
It looks like knitting.about.com was taken down in 2017. It has now been` subsumed by https://www.thesprucecrafts.com/knitting-4162934. I can't find this pattern there anywhere. HOWEVER the pattern is here: http://carole.barenys.com/YokeSweater.html. I eliminated the decorative stitch pattern on the yoke. Carole has other free baby knit patterns!
