Microwaving bottles

[1978andallthat]

Would shaking the bottle vigorously be enough to disperse any microwave hotspots you read about as the reason not to microwave bottles.

I've always microwaved my dcs bottles and swirled very very well and never had a problem - shaking can increase bubbles which can make colic worse. However I only heat until very slightly luke warm - an 8oz bottle straight from the fridge (so very cold) I only do for 55 seconds.

I've been doing newborns for 20 secs to take edge off. Wondered about the bubbles though.

Dd is 2 and I do for 35 secs
