0–12m1–2 yrs2–3 yrs
What to Avoid
- Thawing or microwaving warm purees inside polypropylene (#5) plastic tubs that shed millions of microplastic particles under heat
- Single-use disposable foil-lined plastic squeeze pouches that cannot be inspected inside for mold
- Thin soda-lime glass jars without protective silicone sleeves that shatter under thermal shock from freezer to warmer
- Cheap silicone freezer trays with white pinch-test fillers that impart a soapy taste to breastmilk and fruit purees
Testing & Certifications to Look For

Our Picks
Glass Baby Food Storage Jars Set
Plastic puree tubs that stain and warp
Thick tempered or borosilicate glass jars with measurement markings go straight from freezer to bottle warmer with zero chemical leaching.
Tempered/borosilicate glass, leakproof lids with silicone seals, measurement lines
Why we picked it: Tempered and borosilicate glass are non-porous, so they won't stain or absorb odors, and they keep purees out of contact with plastic; leave headspace when freezing and avoid sudden temperature jumps.
Platinum Silicone Baby Freezer Tray
Brittle plastic ice cube trays
Pop out exact 1-oz or 2-oz frozen breastmilk and homemade puree cubes effortlessly without twisting or cracking plastic.
100% platinum food-grade silicone, clip-on freezer-burn lid, dishwasher & boil safe
Why we picked it: Flexible platinum silicone pops out frozen portions easily and handles freezer-to-dishwasher temperatures without cracking like brittle plastic trays.
Stainless Steel Silicone-Lid Food Containers
Melamine & plastic daycare snack cups
Featherlight 304 stainless steel bowls and snack cups won't shatter when dropped from a high chair and meet strict daycare no-glass rules.
18/8 (304) food-grade stainless steel, leak-resistant LFGB silicone lids
Why we picked it: 304 (18/8) stainless steel won't shatter like glass when dropped, which is why it's a good fit for daycare, and it doesn't stain or hold odors.
Reusable Silicone Baby Puree Pouches
Single-use plastic applesauce & puree pouches
Wide-mouth platinum silicone pouches fill in seconds with homemade smoothies, applesauce, or yogurt and scrub completely clean in the dishwasher.
100% food-grade platinum silicone, wide bottom/top opening, choke-safe cap
Why we picked it: Wide-mouth silicone pouches can be scrubbed fully clean and reused, replacing single-use plastic pouches; check that the spout and cap are sized for your child's age.
FAQs
Why should I avoid heating or freezing baby food in BPA-free plastic containers?
Peer-reviewed studies show that even 'BPA-free' polypropylene (#5) baby food containers release millions of microplastic and nanoplastic particles per square centimeter when exposed to hot purees, steam sterilizers, or repeated freeze-thaw cycles. Glass, 304 stainless steel, and platinum silicone stay inert.
How do you prevent glass baby food jars from cracking in the freezer?
Never fill a glass jar past the embossed 'Max Freeze' line (leave at least 3/4 inch of headspace for liquid expansion), let hot purees cool before sealing, and thaw in the fridge or lukewarm water rather than boiling water.
How do I get soap smells out of silicone freezer trays and pouches?
Use fragrance-free dishwasher detergent pods (artificial citrus/floral dish scents bind to silicone oils) or bake 100% pure silicone items at 250°F for 20 minutes to volatilize any trapped food or soap odors.
