I assume the bows are to show the baby is a girl, not a boy. Still not necessary.
Actually some indication of the sex is a very good idea with infants. After all, we can't go around taking off their nappies!
And honestly it is hard to see whther the infant you are looking at is male or female, now that new mothers don't either colour-code (blue for a boy, pink for a girl, except in Belgium where it was the other way around,) or put little boys into bonnets which came to a point in the middle of their foreheads, while little girls wore bonnets without a peak.
In my experience, new mothers become very offended indeed if you say, "oh what a lovely little girl" and the child is a boy or "oh what a lovely little boy" and the child is a girl!
And asking if the baby is a son or daughter invariable provokes the offended response, "Can't you see she is a girl orhe is a boy." "no dear, I can't - I wouldn't have asked if I could."
So I am all for some or other distinguishing sign.
