So, my one piece of advice as a second time mom is that if you're having a baby in the spring (March), don't just get short sleeved onesies. After you have a baby you usually get the sweats from hormones. That meant I kept my house really cool, even in July when my DS was born. I didn't have a single long-sleeved outfit and ended up having to send someone out to buy them.
I thought I'd share in case this helps anyone.
Re: Random advice from a second time mom
Yup, this, but it was every night for over a week at right around 10pm. I'm not a big sweater normally, so it freaked me out the first few times to wake up dripping in sweat head to toe. I finally just got used to it and expected it. LOL I always knew when it was 10pm. Oh the memories I wish I didn't have to relive each time....
