What is the Best Treatment for a Forehead Scar on a 2.5 Yr Old?

My daughter fell and hit her forehead on a coffee table last night. ER doctor gave her 3 stitches and said it was a superficial incision. We were told to remove the stitches in 5 days (Monday? Since pediatrician is not open on saturday or Sunday). What is the best and safest treatment after stitches are removed? and should I have her stitches removed at 4 days or is waiting until Monday, 7 days, be better? Thank you in advance!!!
