The other day Luken decided he liked when his sister wrapped him up like a baby. They each took turns holding him and we all called him "Baby Luken".
As you can see, Makayla found him a mite heavy. He now weighs 30lbs to her 45lb. I give him two more years before he is bigger than she is. He may not be taller, but I am thinking he will be big enough to take her out if he chose.
