When my aunt have her baby sleeps, she sings to it while it suckles. It's very sweet to see her and any mom to that to their kids. It manifests their genuine care and love for their children. But I think not all moms are sweet to their babies, as I've seen in some cases that whenever their babies are crying, they wouldn't even bother to carry their babies and figure out why they are crying. They would just leave them in their cribs and give them something to suckle until they get tired and eventually fall asleep. I hate moms who are like this. But I can't do anything. I couldn't tell them what to do, as I think they have their own reasoning for doing what they are doing. Maybe their culture is just different from the one I grew up in.
