Hello, I understand your concern
Please don’t worry. For now, no tests or treatment needed. You did the right thing by stopping—your baby will be fine.
Heating milk in plastic bottles for a few months is unlikely to cause long-term harm, especially since your baby is growing well and you’ve stopped it now.
Why we avoid heating plastic: Very hot water/electric kettles may cause some chemicals to leach from plastic into milk.
Next Steps
Bottle feeding is not recommended, you can shift to cup and spoon feeding instead.
Warm milk separately in a bowl/cup and then transfer to the bottle
Use glass or stainless-steel feeding bottles if possible
If using plastic, choose BPA-free, good-quality brands, avoid scratches/damaged bottles
Never microwave or boil plastic bottles
Health Tips
Only if baby has feeding issues, vomiting, poor weight gain, or any new symptoms — then contact your pediatrician.
