When pregnant (or expecting to adopt), subscribe to as many formula companies as possible. These companies send out samples hoping to bank on your purchase of their product later.
If you breastfeed, they are good to keep around for emergencies. If the baby is always on formula, they are great for a weekend get-away. The 8 oz cans last about two days of travel and a 12 oz can lasts about three days! They containers are still sealed when you leave the house, so you can even pack them in your luggage or carry on when flying.
My granddaughter is 5 and when her mommy was pregnant I went to a site called freestuff.com and got a 1 year subscription to American Baby. I don't know if you can still do that but it's worth a try. as a result of this we both got samples in the mail on a regular basis ... diapers, wipes, baby food coupons, etc.
If you like the convenience of the individual packages of powdered baby formula but don't want to pay the price, measure out scoops of formula into empty M&M minis tubes. The smaller tube holds enough for a 4 ounce bottle, the larger tube holds enough for an 8 ounce bottle (you must pack the formula to get the 8 oz amount to fit). The tube fits easily into the corner of a purse/diaper bag and doesn't take up as much space as those round containers that hold 3 servings. The tubes are also good for holding raisins, goldfish, other snacks for toddlers.
I love this idea! However, I sanitized and ran a tube through the dishwasher, and it still smells like chocolate. Should I be worried it will get into the formula?
