I have to say I'm one of those friends who would be very blunt. There is no sugar coating what is best for the baby. She sounds like all her wants are quite selfish and immature and being a mother is about putting a little person first regardless. She definitely sounds like she could benefit from a person who isn't her friend (and perhaps a bit older, like her mums age) telling her the reality of it.

I don't think it's fair to say she is selfish. Her attitude could come from how she was brought up or the parenting influences around her. I grew up hearing how I was shut in my room at 2 weeks old to teach me a lesson and it didn't occur to me how wrong that was until I had my own baby in my arms.
