The hazard is actually not great. Babies would need to consume the contaminated water for a long time before showing measurable harm. Since the radioactivity has a half-life of 8 days, that's not going to happen (unless something else goes wrong, which is unlikely now).

The Japanese government are being excessively cautious again. See for example World Nuclear News.
