Congrats!!!! I'm over the moon for you guys! I'm clearly not a guy, but I've heard my hubbs talking to his guy freinds and it usually goes like this...

"Just enjoy it. Have fun with it, She may curse you out, let her, then rub her back or feet or leave her alone. Whatever she wants, cuz ya know she's going through making a human being, and that's crazy. Just be your best for her and the baby and take pics and eat pickles and ice cream and buy crap you don't need cuz it's all amazing and all worth it".

hope it helps lol
