I always wanna give my kids things to learn and better themselves so we have decided to start learning and teaching our 2.5 yr old and baby sign language. My toddler already knew some from the library storytimes but has picked up about 10 new ones in the last 2 weeks. My 4 month old doesn't do them but seems to understand what a few are. So much fun to learn with her but also see how quickly she learns. If she keeps picking it up so fast we will find her a real teacher but right now we are learning all sorts of useful words. I know about 100 words, alphabet, numbers but am hoping to also be fluent someday just for my own accomplishment and personal development. Learning is so much fun!!!!
