My sweet niece is a nurse-in-training! She is always very interested in how Abby's machines work and the things we do to take care of her. The other night while we were on vacation, I allowed her to suction Abby with me for the very first time! (With a lot of help and supervision, of course!!!)
She has her own trach baby doll, so she practices suctioning and changing the trach on her. She's quite a little nurse-in-training, and I wouldn't be surprised at all to see her grow up to be a nurse or a doctor one day!
