"Checkin' Up On My Baby" is a blues song by British musician John Mayall and his band The Bluesbreakers. The lyrics tell the story of a man who has been away from home for a long time and is finally returning to check on his girlfriend or wife. He is suspicious of her behavior while he was gone and wants to find out what she has been up to. The song opens with the man saying he is "checkin' out" his baby, which means he is going to investigate what is going on with her. He notes that he has been out of town for many nights and days, implying that he has reason to be suspicious of his partner's behavior while he was away. In the chorus, the man repeats his desire to find out what his baby "puttin' down," meaning what she has been doing while he was gone. He notes that he wouldn't come home or even write, which further suggests that he is upset with his partner for some reason. The last verse repeats the previous lines about not coming home or writing, but adds that the man caught a plane and flew back when he became suspicious of his partner's behavior. The song ends with the chorus, again emphasizing the man's desire to find out what his baby has been up to. Overall, "Checkin' Up On My Baby" is a classic blues song about jealousy and suspicion in a relationship. The man is worried about what his partner has been doing while he was away, and is determined to find out the truth.
