I'm not sure if the safety aspect on take off and landing, it used to be accepted.
I think this however is trying to infer the problem is breastfeeding per se and not the timing?
Now if the crew were wrong and it's not breaching safety they need to be told,, it was certainly not the case of not being able to breastfeed at other times. I'm not sure if the not during take off and landing would make me overly anxious about flying, although a crying baby is stressful.
