I use hot water to warm the bottle up. It’s not hot but warm
My mom figured out my kid takes it straight from the fridge. He was too impatient once and wanted it and so she gave it thinking he wouldn’t like it but ever since then… cold
Yeah my baby drinks it warm, cold and at room temp. Just depends how he is feeling!
I think the milk just needs to be at same temp to mix
If your baby will take it cold that’s great! It’s not required to be heated :) and yes you can do that! It’s recommended to cool the fresh milk first before adding it to the older milk
