It's been my experience that the food balance can get a little tense in the earlier stages of the game, especially when you have made a bunch of babies (kids seem to eat as much as adults)! As long as your villagers are in relatively good health now, they will probably not starve to death before the crops appear again. You might check the berry bush to see if there are any meager supplies of berries (just in case). Hang in there! After the food crisis is over, you might want to work toward getting that third food source as soon as you can!
