With my first baby, it didn't really change that much until two days before his birth - DH commented that by looking at it, he would be surprised if I didnt' have the baby within the next two days and he was right. Dh has pulled many calves and lambs on the farm and he said you can always tell when a cow is about to birth as her vulva starts protruding and looking really puffy (I hate having to use that analogy but it really is true).
LOL Sherie! I thought the same way as your husband- Before I gave birth that's what it reminded me of too! It really is very similar to when cows are about to have a calf! Guess we are animals too aren't we
