You both are adorable! It's amazing your girl is five months old! Cherish these moments, because that first year goes by way too fast.

Stop beating yourself over your looks, you're growing into yourself. You're thinner now than you were last year (pre-pregnancy), I guarantee you'll be as gorgeous as your sister not too far into the future! <3

I think it's wonderful you're doing this, being just 15/16, and thank God your sister and mother are there giving you all their support. That's awesome, you're very lucky and Aurora is even luckier to have not only a loving mother but a loving aunt and grandma as well.
