I thought 5 would be the perfect number for us, but I still feel like we aren't done yet! I kind of hope I can have another set of twins to finish off the family, just bc that way we won't have one kid alone (which is a concern for me after having all my other children in "groups"). Dh and I are pretty sure my uterus can only take one more pregnancy after all its been through, so I guess I need to start praying that lightening will strike our family twice with another set of twins!!
As for having them close in age, I would LOVE it! I adore having mine all as close as they are (even with all the chaos that is an everyday part of our life now) and I am hoping that I get my first ppaf back one of these months! We are really hoping to start ttc in September and hopefully we can succeed at having our last child(ren) less than 2 years apart from the rest.
