As a mom to a baby the NICU nurses dubbed "houdini weenie" (LO somehow managed to pee into the glove of a nurse who changed his diaper and used to pee all over his isolette as he was so sneaky) wet wipes are your friend. Just have the new diaper ready and a wet wipe over the willy. Use diaper rash cream at the first hint of red. LO has never had a big rash thanks to this.
Don't buy a lot of outfits until they're about 6 months... LO lived in sleepers and onesies as they're so much easier to change him in and for him to sleep in. Now it's a lot of fun to dress him up as he's more active.
don't feel guilty if you decide to formula feed or breastfeed. Just research your best options for your situation and find someone who can offer you support. There's too much pressure on this subject and you'll be judged no matter what (at least on forums anyway)
Take LOTS of photos and baby memory book.
If you have an OH/DH, make sure you let him know that he needs to help out and don't let him slack off. Guys get used to being lazy if we let them.
If baby is crying nonstop, it's ok to put him down in a safe place, close the door and walk away to collect your thoughts for a few minutes. Really. take a few deep breaths and repeat "this too shall pass"
Chocolate is your friend.
Weight loss isn't always as easy as some would make you think. Drink lots of water and don't munch on everything in sight (like me). Walk if you can, it really helps energize me and calm LO. I think the fresh air makes babies sleepy!
Don't let anyone push you around! You're the mom- not them. This also includes online too lol.
Make mental memories.. Sometimes I try to make it a point to take a mental memory of LO sleeping or doing a milestone. I don't want to miss out on anything!
That's all for now...
