Hi Jill, Sophie, and Tigger! Welcome to TCS!
How exciting that you're looking to add a little bundle of love to your family! With older kitties in the home, it should be a ton of fun to have a baby in the house again. I'm easing out of the baby stage with my almost 9 month old kitten, Finn, but I look back fondly on all of his crazy antics! I was lucky that my older kitties (though they were all under the age of 3) took to Finnegan rather quickly and I wish you the same luck with your new baby when he or she arrives. Do you know what type of kitten you're looking for or what age? Do you have ideas on colors, names, or what sex of kitten you'd like? Looking for a new family member is so much fun. I think I'll live vicariously through you though as I'm at my limit with four kitties in the house

(among other animals).
Please keep us apprised as to how the search is going. And, yes, post pictures as soon as you can! I look forward to getting to know you, Sophie, and Tigger in the future. And, welcome again to TCS!
