Hi dear, normally I just keep my express milk in the bottle. I didn't use towel or keep inside warmer bag so far my baby is doing well. normally we go to shopping, so is in the air con room . Even our weather is very hot, but all the places , normally is fully air con.
The milk you pump out can keep up to 4 hours in room temperature.
For the milk from the fridge , I just warm it when my baby want to drink . after warm, I put keep it in the room temperature, or if I want to go out . I just put inside my shopping bag, normally I will let my baby drink within one hour. I didn't warm it again when my baby want to drink.
I didn't put in the warmer bag. After warm just keep in the room temperature within one hr , my baby will finish the milk.
Okok.. Well noted. Thx fr sharing ya. Hehe
