Ay, sobrang importante yan! A few of us mums swear by silicone teethers kasi they're soft, easy to clean, and walang BPA, si Maria's boy loved the ones from Mothercare and Toys R Us, tapos ang iba namin nag-try ng wooden teethers din na from Lazada sellers na verified (just make sure walang paint na toxic). One thing na tried and tested talaga is putting a clean, wet washcloth in the freezer para i-chew nila, super convenient at free pa! TYSM din, hope this helps with your baby's teething phase!
