Your problem is lack of light and a camera which is noisy over ISO 400.

What you can do:

1. Keep ISO at 400, underexpose the shot but around -0.3EV and keep shutter-speeds at 1/3-1/5s for an almost still baby. This will give you an underexposed slightly grainy shot.

2. Open this in PS and use NR software like Neatimage (my preferred tool). And use levels to increase the exposure to your heart's content.

3. Do NOT use zoom, ensure your aperture is always set at f2.8 for the highest shutter speeds possible. If you're using zoom you need more light or more ISO to have proper exposure.

That's the best you can do. I do not recommend tripods since your baby would move eventually. :-s

BUT an even better way is to try bouncing flash off the ceiling. If your pop-up flash goes high enough, place a white cardboard under the flash and take a shot with flash so that light bounces off the ceiling. Raise ISO to atleast 200, ideally 400. Use NR software again. I can show off some wonderful shots I have taken with this technique.
