Is it normal for 4 year old girls who have only taken about 2 months of gymnastics (once a week mostly) to be doing really good cartwheels, one-armed cartwheels, round-offs, one-armed roundoffs, (I think it was called a pull over), and they do something like a handstand and fall into a bridge and kick back over? My girls were just invited onto team and when I asked about pre-team the lady was pretty adamant they should be on team...since we just started I would love some input...they do seem to have a natural ability.
