Fred Thomas of AllMusic gave the album a positive review, saying "DaBaby's charm lies in how he's not even taking his irreverent cockiness too seriously, much less asking his audience to bow down to his greatness. Springy, uncluttered, and unable to contain its own grinning excitement, Baby on Baby zooms by in a captivating rush."[9] Marcus Blackwell of HipHopDX rated the album 3.8 stars out of 5, saying "DaBaby has staked his claim as an artist by developing a compelling balance of street and lighthearted content that effectively highlights his personality. Baby On Baby at its best delivers an energetic, fun sound that stands out in rap's current landscape, making for a refreshing listen."[10] Paul Thompson of Pitchfork, rating the album 7.7 out of 10, said "Baby on Baby comes in the middle of a prolific period for the rapper [...] the music is refreshingly without pretense or artifice, concerned less with the way it will play in boardrooms and more with the way it will play out of trunks."[11]
The album debuted at number 25 on the Billboard 200 albums chart in the United States, before eventually rising to number 7.[12] As of July 2019, the album has earned 473,000 equivalent album units.[13]
