Logan has been working on sitting (so far he sits in a boppy for about 1 minute at a time!!!!)....my goal is to have him sitting by his 6 month evaluation by Birth to 3, which is at the end of January. Sitting was one of our goals, along with a few others that we will work on as well. Also, his favorite thing right now is sucking his thumb...his left one. It is so cute, but I am working on having him take a pacifier so that I don't have to break a bad habit later. The thumb sucking is great when it's time to go to sleep. I just put him in his crib, he rolls to his belly, pops it in and goes right to sleep.
