9mth old baby starting to stand and move around and fall and hit her head. Should I let her cry it out? I've heard both advise for soothing her straight away and completely ignore her so she can learn - any advice?

Dont react to every fall. If the baby is not crying and staring at you. Keep a straight face or react a positive way. To show it’s ok to fall and it doesn’t hurt. If crying just tell ask her what happen and explain what caused her to fall. Next time how she can prevent it by showing her what she can do. Babies understand more than we think they dont.
