Depending on how close you are to your subject, 50mm is good. Certainly in the classic portrait role - head and shoulders, in darkened room etc. the 50 is ideal. I think if you're trying to get shots of your youngster once it starts crawling around etc. the wider 35mm will be more versatile. Indoors in particular, 50mm is pretty tight, and may not get enough of the scene.
I think you might want to get the kit zoom first, set it at 35mm and then at 50mm and see what the field of views are. It may not be exactly like the prime, but very close in view. I think you'll find you want wider than 50mm for most work.
Another good option you could pursue if you want an upgrade from the kit lens is a DA 16-45 zoom. That's a great lens indoors, very wide to relatively tight. Not extremely "fast" in aperture, but with the new sensors it's just fine in reasonable light. It's pretty sharp, too.
I'll note that I don't have the 35 or 50. I have older manual 50s. I have a 21 and a 28mm lens as well, and often the 28 is a bit tight if you're indoors at events trying to get group shots. I do have the 16-45 and when taking pictures indoors was rarely over 30mm.
