Let me start by saying these little glass jars have been a game-changer in my kitchen. As a parent who meal preps for my toddler, I can't believe I waited this long to get them!

The 4oz size is perfect for single servings - not too big, not too small. I love that they have measurement markings (up to 2oz) which makes portion control super easy. No more guessing how much applesauce or puree I'm packing!

The glass feels sturdy and high-quality - definitely not that thin, cheap glass that chips easily. And the silicone seal? Amazing. I've tossed these in my diaper bag multiple times and never had a leak, even with runny purees.

Stackability is where these really shine. My fridge used to be a mess with random containers, but now I've got a neat little tower of these jars. They save so much space!

Heating tip: The glass warms food evenly in the microwave, but remember to remove the lid first (learned that the hard way when I melted one slightly). They transition from freezer to microwave like champs after a quick thaw.

Bonus use: I've started using them for my own salad dressings and spice mixes too! Way cuter than plastic takeout containers.

Only con: The lids aren't dishwasher safe, but handwashing takes seconds. Small price to pay for such versatile, durable containers.

Final verdict? Worth every penny. These have simplified my meal prep routine and reduced so much food waste. If you're starting solids or just need better kitchen organization, grab these!
