I charge the same price no matter the age of the child but parents have to supply all baby food and bottles so there's no cost at all for me for babies so I have a higher profit already because I'm not supplying their food. That's the way I see it anyway. The youngest baby I've ever accepted was 4 months old and I admit I was very nervous about it. Sunnydays made some good points that I agree with for such a young baby. Be careful.
