It's such a great feeling when they accomplish something when they have been struggling with! I thought my daughter was the only one who took so long to do something! She has had her BH for 3 years and until last October when she actually did a ro/tuck, but it was only that one time and then she hurt herself right after and had a severe strained muscle in her lower back...since then she has been afraid to do much and even stopped doing her BH for a while. May of this year, she finally did her standing tuck. She doesn't land it all the time, but it is pretty consistent. Last week she finally has her ro/bh/tuck consistent....took us 4 years of cheering/tumbling but we are finally begining to see the light.....so never give up hope!!!!!!
