An extension of the theme from the group's #1 hit "My Girl", which had been released the previous December, "My Baby" features The Temptations, with David Ruffin on lead, bragging about the qualities of a special lady. Ruffin praises his woman's hairstyles ("hair soft like a baby lamb/and I love to run my fingers through it") and personality ("the gold in her personality/could set Fort Knox to shame"), and hopes that "she digs me the way I am/but if I have to change/you know I'm gona do it for my baby".
Cash Box described the single as an "easy-going, pop-r&b romantic shuffler about a love-sick fella who’ll do anything for his girlfriend."[2] "My Baby" was a notable attempt to create an uptempo danceable number for the Temptations; all of their previous Top 20 hits to this point had been either ballads or mid-tempo numbers. The single immediately following "My Baby", "Get Ready", followed the same plan, and was produced with an even faster tempo and a brassier arrangement.
Unusually for Temptations singles, "My Baby's" B-side, the Paul Williams-led "Don’t Look Back", was a minor hit in its own right, becoming a top 20 R&B hit and serving for several years as the Temptations' live-show closing number. Both sides of the single would be remixed for its 2nd pressing, adding on the following statements: "Taken from the album #G 914 The Temptin' Temptations."
