looking for 1979 song from chicago area

Hi..Long shot here..I'm looking for any info on a song playing on local chicago stations way back in 1979..It was a country song that I have yet to hear again since then..I'm assuming it was a local artist and I have been wanting to hear this again since I first heard it 30 years ago..Anyone who thinks they would be interested in helping me would be truly appreciated...It's basically a song about a guy who finds out his wife is pregnant and he sings about the things he is going to do with this little cowboy..At the end, his wife has a baby girl and the guy says this is what he's always wanted..a little "cowgirl"..
