Parents making a facebook account for their baby is a great way to get more attention for themselves as if having babies is a talent. Plus this way in a couple of years when the cute baby becomes an aggravating kid no one is impressed with, the parents can still look back at the baby’s profile remembering a time people gave a shit about their family.
Also, your baby being cute is nothing to shout out to the world about. Every baby is cute and in fact I can’t even tell babies apart. Then again I try to avoid them all together.
