Been there, done that. DD was about 2 and her bangs grow FAST! I didn't want to have to pay money just for a quick bang trim that I could do at home. I was doing just fine by myself until one day she decided to turn her head to look at something just as I went snip. Her bangs were about a quarter of an inch below her hairline. Luckily though, because her bangs grow fast, in a few weeks she was looking normal again. After that, I started taking her to the salon for the cuts.
What is the scotch tape trick anyway??? I've never heard of it.
