Hello & welcome to you & your new little one! I am going to assume (sorry if I'm incorrect) that these are your first retfs. so first off I'm going to give you some reading assignments that will answer most of your questions. When I got my first retfs almost 3 years ago, I used these sheets a ton! Once you have red over them, you will probably have more questions which one of the many retf owners will be glad to answer for you! Enjoy the reading and welcome again!
