When someone lets you hold her two-month-old for the first time, and the baby is asleep and wrapped snugly in a blanket, it is not a good idea to immediately unwrap her. Not even if you declare that "She just needs to breathe a minute." When the baby then starts crying (duh), it is also unwise to tell her mother that "She wants to go home now."
Her mother JUST might smack you. Or at least proclaim your ignorance all over the world-wide web.
