1st Birthday Instagram Captions for Baby Girl or Boy



The first birthday of your baby is a very special day. It is the day your baby grows older, and the day you have to take a step back and appreciate his first year. It is the day you first realized that your baby has grown into an active toddler, and is going to keep you on your toes for years to come. However, his first birthday is also a time when you realize that your baby is going to be your baby forever! And you will love him just as much, if not more, as you do today.
