SIL pregnant

I'm going to be an aunt again! My brother and SIL just brought our 2 yr old niece over with a Big Sister shirt on.

I'm so excited for them, but a little sad. They tried for one month. DH and I have been ttc our 1st for 3 years. SIL is a year older than me, too.

Bittersweet, happy, and frustrated.
