Bottle Feeding
Never microwave your baby's bottle: It could heat unevenly, leaving "hot spots" that could burn her
Test the temperature of heated breast milk or formula by shaking a few drops on the inside of your wrist: It should feel lukewarm.
Hold your baby semi-upright and support her head when you give her a bottle.
Get her to open her mouth and latch on to the nipple by gently stroking her lower lip or cheek with it.
Never "prop" your baby with a bottle.
Feed your baby as much as she wants--but not more. She'll fidget when she's full; she'll smack her lips when she's still hungry after draining her bottle.

Essentials for Bottle Feeding

Choosing which formula to feed your baby can seem as complicated as selecting a fine wine for a dinner party (remember those?!). Ditto choosing a bottle to serve it in. We're here to help--with some tips about finding the right bottle, nipple, and formula for your baby, plus a list of other essentials to have on hand. (Note: This advice applies if you're breastfeeding and supplementing with formula, or pumping milk to give to your baby in bottle.)

Size matters most, depending on your baby's age. Buy smaller (4- or 5-ounce) bottles for your newborn; switch to larger (8- or 9-ounce) bottles when she's around 3 months old. Then consider shape (angled bottles make it easier to feed a baby in a semi-upright position; older babies who can hold the bottle may find it easiest to grip the "waist" of an hourglass-shaped one); small parts (the fewer the better--as in fewer bits to lose and clean); and reusable versus disposable (disposable meaning plastic liners that fit inside reusable holders).
Of course you'll want to make sure the nipple you choose is compatible with the bottle you use, and the right "flow" for your baby (newborns need a slow flow, older babies can handle a faster one). Beyond that, think about what it's made of (your choices are latex, which is tan in color, soft, and flexible; rubber, which is durable but not as flexible; and silicone, which is clear, firm, are can be boiled) and how it's shaped: A long rounded tip is easiest for most babies to suck; flat-on-top orthodontic nipples are thought to be most like mom's nipple.
Unless your baby is a preemie or has a health problem that requires a special formula, your choices boil down to cow's milk or soy-based (only recommended for babies who can't digest lactose or have a milk allergy). What you will want to think about is whether a formula is fortified with iron (that's ideal); has DHA or ARA (additives that are thought to boost brain development); or is organic. And since you'll be the one prepping your baby's bottle, consider whether you want the ultra-convenience of pre-mixed formula, or a less pricey powdered one (which gets points for being easy to bring along on outings if you're sure you'll have a safe source of water to mix it with).
Most babies are perfectly content to suck down dinner (or breakfast, lunch, snacks) straight from the fridge. But if you prefer to take the chill off, a bottle warmer will make for easy heating. Some features to consider: an automatic shut-off, an indicator that signals when a bottle's warm, plug for a car cigarette lighter for on-the-go heating, compatibility with different sizes and shapes of bottles.
Plain cloth diapers are soft, easy to wash, and won't blow your baby budget. Plus, they're great for dusting when you no longer need them for spit-up duty.
When you have to hand-wash bottles (or simply want to), nothing beats a long-handled, skinny round brush designed precisely for that purpose.
These clutter cutters come in a variety of sizes and configurations, so think about how much countertop you can afford to give up; look for a collapsible one if space is really at a premium. And make sure to buy a rack that will accommodate small pieces (nipples, bottle tops, pacifiers, etc).
Cut down on bottle-part casualties by putting nipples, lids, and other small pieces in a closable basket that fits in your dishwasher.
Baby bottles will get plenty clean in the steamy heat of the dishwasher, but if you don't trust yours to do the germ-torching trick, you may find that a bottle sterilizer is a time- and-laboring saving alternative to boiling bottles on top of the stove.
By the way, mealtime is prime bonding time, one of your best opportunities to really take a good, long look at your child. Check out her perfect little nose and ears, stare into her big baby blues, tell her all the wonderful things you have planned for her.
