1) Nap time is sacred.
I mean that quite literally. Don't be offended if you call me during nap time and I don't answer. Or I answer but only talk briefly. It's that amazing (yet always too brief) part of the day where you can shower, eat, clean the house, catch up on your TV shows and try to relax. Like I said, sacred.
2) You can sweep the floor five times a day and still have crumbs everywhere.
I remember thinking it was odd that one of my friends had sweeping the floor on both the morning and afternoon chores list for her kids. But seriously. When there are children roaming free in the house, you can sweep all day long and still have food sticking to the bottom of your feet when you walk around barefoot.
3) You will forget what life before kids was like.
Being able to leave the house on a whim? Spontaneous weekend getaways? Enjoying a nice quiet candle-lit dinner at home? Those things will all seem worlds away, like a dream that you are unsure of whether or not it actually happened.
4) It is impossible to have nice things.
That cute shirt you bought on a killer sale? NEVER wear it unless you want it to be covered in ketchup, yogurt, or blueberry stains. Your smart phone/tablet/laptop? Hide them. Up high. And don't ever let them be seen. Those cute lamps that you spent hours refinishing? You have two options: 1) put them in a storage until for the next 15 years or 2) take a picture for posterity and then give them a kiss goodbye.
5) Your house will never be clean again.
Your perfectly decorated house will be cluttered with an endless amount of baby things. It starts with swings, bouncers, burp cloths and diapers. Soon it turns into jumpers, bumbos, high chairs, books, stuffed animals and toys. Add a cute little crawler or walker into the mix and you have a constant "my-house-looks-like-it's-been-hit-by-a-hurricane" feeling.
6) Picking someone else's boogers isn't as bad as it sounds.
Neither is cleaning up a child with poop up their back. When it's your own child, it's not weird. It's just life. I remember watching my sister pick her daughter's nose and thinking that it was the most disgusting thing I'd ever seen. Now it's a nearly daily occurrence for me.
7) Everything in your house is deadly.
If your kids are awake and let loose in the house, you will never go outside for long. You will constantly be worrying that they will pull over that 300+ pound entertainment center that you have yet to secure to the wall. Or that they will eat something nasty out of the garbage. Or fall and hit their head on the corner of your $7 Ikea end table. Basically anything in your house could kill your child.
8) Hanging out with friends is nearly impossible.
You swore you would be the cool parents that would still go hang out with your old friends and do pretty much anything you want. Oh wait what about nap time? It's sacred, remember? And then there's the time you need to breastfeed. Can you do that easily where you're going? Now make sure you pack enough diapers, wipes, burp clothes, bibs, toys, books, spare change of clothes, snacks etc. in the diaper bag. Got it all? OK go. Then once you get to wherever you're going, your child decides they want to scream the whole time. So you go home, probably before even really getting to see your friends. And you decide just to stay home next time.
9) You never knew what love really was.
Your heart will hurt with how much you love your little mini-me. And your love for your spouse will grown and change too, when you see how much they love your little one. You will be overly emotional about any potential harm that could come to your child. And you will be completely irrational. You would literally do absolutely anything for your baby.
10) The laundry/dishes/housework will never be done.
You will no longer be able to get away with doing one-two loads of laundry a week. It's a daily thing now. And the dishwasher will be run on a daily basis. You should vacuum at least weekly but you don't. You will pick up toys all day every day and still miss some. You will have a pile of folded laundry that sits outside the baby's room all night (and maybe for the next few nights) until you get a chance to go in and put everything away. And folding all those teeny tiny baby clothes is pure misery.
