The last year has been such an amazing roller coaster for DS1 who is now 3.5 years old. He has gone from being a baby to a kid seemly overnight. One year ago, he was sleeping in a toddler bed, potty training, and still had his binky 24/7. Now he sleeps in a big bed, hasn't worn a diaper in a year and is starting to read! It seems so crazy! How about your LOs? How have they changed in a year?
