FAQ
Will this work for a breastfed baby?
The GentleBottle system was designed specifically for breastfed babies, with a soft squeezable body and off-center nipple that mimics a natural latch to reduce bottle refusal.
What should I look for in a bottle for a newborn?
A slow, controlled flow and a soft nipple that supports a deep latch. The GentleBottle’s off-center nipple angles toward the palate and paces milk like nursing, and the 4oz size suits early feeds, which is why parents searching for the best bottles for breastfed babies so often land on it.
Are glass or plastic baby bottles better?
Both have trade-offs, which is why we chose a third material. The GentleBottle is 100% food-grade silicone (free of BPA, PVC, lead, and phthalates), so it won’t shatter like glass, and the soft body compresses in a baby’s hands like skin. It goes in the dishwasher (top rack) or a steam sterilizer without breaking down.
When should babies stop using bottles, and how do we wean?
Pediatric feeding specialists suggest weaning off the bottle by 12-18 months, and gradual works best. The GentleBottle Transitional Set moves from nipple to teether handle to sippy lid on the same familiar bottle, so your baby changes one skill at a time: the sippy lid turns it into a soft-spout cup for the transition from bottle to sippy cup, and open-cup practice can start around 6 months.
How often should I replace bottle nipples?
Inspect nipples monthly and replace roughly every 3 months, or sooner if you see thinning, clouding, or tears.
Is this safe for my baby?
Yes. Olababy feeding products are made from 100% high-purity food-grade silicone with no fillers, free of BPA, PVC, lead, and phthalates, and tested to FDA food-contact standards.
How do I clean and sterilize it?
Silicone products are dishwasher safe (top rack) and can be sterilized in boiling water or a steam sterilizer. Air-dry fully before storing.

Our material
“Food-grade silicone” is a purity standard, not a marketing phrase. Olababy uses 100% high-purity food-grade silicone with no fillers, free of BPA, PVC, lead, and phthalates. Unlike plastics, silicone is inert: it doesn’t leach chemicals when heated, sterilized, or chewed on, and it stays soft on developing gums and teeth. Every batch is tested to FDA food-contact standards, and every product is dishwasher-safe.
