It doesn't sound like a big deal but I was terrified of messing it up lol. I cut my husband's all the time, but I wasn't sure I would like a "high and tight" on my almost 2 year old :P I initially just cut it with scissors (after watching some YouTube videos!), but decided to take the clippers to it the next day. I did an 8 on the top and a 6 on the sides and back. It looks adorable! His very first hair cut was 1 cent at this kid's hair cutting place. But this one was free (well, minus what it cost me in electricity to run the clippers, lmao).
And I trimmed my own, and I have to cut my husband's this weekend.
