When I bought formula the first time I got the most expensive one on the shelf. I totally thought brand name formula was better for my baby and wanted to give her the best. Since then, I learned that all formulas are required to meet the same nutritional standards, set by the Food and Drug Administration (FDA). Store brands provide all of the nutrients that babies need, just without the expensive price tag or marketing budget. The best formula for your baby is the one that works best for them, and for my daughter it also happened to be the cheapest. Score.

I learned, albeit the hard way, that your baby might not like fancy, expensive bottles. It turned out that my youngest son will only use the free nipples they gave us at the hospital. I really regret buying a dozen fancy ones before he was born.

Don't make your own formula. Again, for the people in the back: don't do it. I thankfully knew to not follow this advice, and I wish people would stop sharing it. It's a horrible idea. Commercial formula is safe, healthy, and expertly formulated to meet all of your baby's need. There's no reason to make your own, and it can seriously hurt your baby or make them really sick. Don't do it.

With my first baby, I boiled bottles to sterilize them. I thought I had to, but nope. Not only does it take extra time and energy I don't have, it's totally not necessary. Soap and water, or the dishwasher, is just fine.

I received so much conflicting advice about what kind of water to use to make formula — bottled, boiled, or straight from the tap. After a bit of research, my partner and I decided to follow the Center for Disease Control and Prevention (CDC) recommendation to use boiled and cooled tap water when our baby was small, and then switch to filtered water from our fridge when he was older.

When my daughter was born I was such a crunchy mom. I honestly thought that organic formula had to be better than any other formula. It turned out that organic formula, in addition to being way more expensive, gave my daughter horrible constipation. I learned that organic formula isn't necessarily better, healthier, or anything other than marketing and a heftier price tag.

When my daughter was a newborn my partner and I were told to feed her on a schedule. I got so stressed out when she refused to eat every three hours, or ate more or less than the chart said she should. Once I ditched the schedule and fed her when she was hungry, and as much as she wanted, she was so much happier. You really can't overfeed a baby. They will, you know, let you know by spitting up all over you.

When my daughter was born my friend told me that you should mix bottles as you use them. I soon ditched that advice and started making a day's worth of formula each morning. Not only did this save time, but I no longer had to make bottles in the middle of the night and that was amazing.

I wasn't planning to stop breastfeeding at age 1, why would I stop bottle feeding? When my son turned 1-year-old people immediately asked me when I was going to take away his bottle. I really didn't know what to do. I mean, he loved his bottle. It was totally his lovey. I am so glad I let him decide when he was ready (at about 18 months) to ditch the bottle, rather than forcing him to say bye to his "baba" based on some arbitrary advice.

So, yeah, this one is totally up to your baby. I thought I had to warm bottles for my oldest, so I did. Then, when my second child was born and I ended up giving him a room temperature bottle in a pinch. Guys, he loved it. He ended up liking just about any temperature bottle — from ice-cold to toasty warm. It made things so much easier to not have to warm up bottles for him.
