Affectionate Husband

My husband has been more affectionate now after our baby girl was born. Has anyone else experienced this? Like we were super into PDA and he was affectionate before but he is a man’s man & football coach so I knew he isn’t really the affectionate type when I married him and now he is being super lovey dovey and sometimes I feel bad but I feel like he is being too affectionate and I don’t understand what changed. Don’t get me wrong I’m not complaining and I love that his love for me didn’t go away after child birth and pregnancy, but is it normal for men to become more affectionate after a baby is born?
