Robert Copsey of Digital Spy gave the song a positive review, calling it "effortless and uplifting" and awarding it four out of five stars.

[2] In another four-star review, Renowned for Sound's Melissa Redman complimented the song's "exceptional vocals", "perfect harmonies" and "mature lyrics".

[3] Isaac Mace-Tessler of Pop Scoop gave the song a very positive review, saying "'Little Me' has a strong message of inspiration and liberation, all about the girls' present selves telling their younger, little selves not to worry and to 'speak up, shout out, be a bit prouder' and believe that they are already 'beautiful, wonderful'.

The track thus follows and holds its own in the grand tradition of R&B empowerment ballads such as Sugababes' "Ugly", Destiny's Child's "Survivor" and Christina Aguilera's "Beautiful".

Little Mix performed "Little Me" on The Xtra Factor on 3 November 2013,[8] and on the Capital FM Jingle Bell Ball on 8 December 2013.
