NO, NO, if you don't want to do it then NO....it doesn't make any difference. If you love it how it is then keep it that way. My DS is 2.4yrs & has had 2 cuts....or should say very small trims!!! I love his blonde curls & no one is taking them away. My MIL is always telling me you need to cut it & SIL little girl has had 3 cuts now....big deal...she also has no hair & perhaps that's why LOL!!!! You leave it how you wish.
