Soren is just popping out those teeth, all rapid fire style. Got his first one, then 6 days later got his second one (both lower central incisors) and just yesterday - 8 days after the second one - I noticed a third tooth emerging! This time it's an upper, the right central incisor. From the look of his gums, the left one isn't far behind. So, very soon, the little scraeling will have a matched set of uppers and lowers, all the better to nibble with.
