Comments: OXO Tot’s Baby Blocks baby food storage containers are the number one best seller on Amazon.com. Parents love them. They come in three different configurations: 5-piece, 7-piece and 12-piece (pictured). The individual containers hold 2 and 4 oz. servings, come with measurement markings on the side, and are airtight, watertight and leak proof. Trays are included to keep the containers from rolling around your freezer. The containers are dishwasher (top rack only), microwave and freezer safe and the plastic is BPA, phthalate and PVC free. Readers have noted the containers will fit in Dr. Brown’s bottle warmer.

So how do they work in the real world? Our readers love them. A few parents noted that the containers have a silicon ring in the lid that creates the seal—this ring can sometimes pop out. Food can get stuck in the seal, causing mold. Also, be sure you don’t wash OXO Tot Baby Blocks in the lower part of your dishwasher unless you want melted goo. Despite these drawbacks, we’ll give Baby Blocks our top rating. Rating: A
