We have still 5 snow bubbas left and having just had twins a year ago - I dont imagine that each of these little ones will be given the chance by us. I would like to go again, but DH is not so sure just yet... But in answer to your question I think I would want a third anyway whether we had snowbubs or not - and prior to the twins I would have said only 2, so....

Either way all our snowies will get a chance one way or another as any I dont use myself will be donated to infertile couple.
