Ok, so no pictures yet, but it is DEFINITELY there! Kyle has been a little fussy lately during feedings which prompted me to yet again check the gumline. While I swear I checked the day before, it is now official and his first tooth has broken free. It is on the bottom lower left, where I had been suspecting. He seemed to be eating better today, so it must feel better through the gum than just below.
Kyle also discovered that he LOVES the Jumperoo. Yeah! I thought maybe he wasn't going to take to it, but I think he just wasn't steady enough before to manage the jumps. He is now though... watch him go!
