My daughteres are 4.5, and i've always sworn that I will not have any more kids... almost took care of it permanently about three months ago, but was too busy with vacation etc. Now, I keep thinking about a baby - how my girls would be great big-sisters, etc., and then I thought about the cons: taking two to kindergarden and one to the sitter, getting up by myself at night (hubby works 3rd shift), colds, fevers, bottles, baby food. Well, for now, the cons have settled my thoughts, but I don't feel that they will for long. Maybe its the weather!! However, I do not feel that volunteering or getting a puppy would solve the recurring thoughts. Baby's are yours, puppys and volunterring are completely different. Good luck...
