I found out one sister was pregnant last summer. My niece was born in early February.
I found out another sister was pregnant last fall. My niece was born in early June.
I found out today that my third sister is pregnant. Due in February. It wasn't unexpected. I'm happy for her (them). It wasn't easy for them to conceive. It took two years and several IUIs.
Thankfully I do not have any more sisters (or brothers).
I'm taking it hard.
