Travelling through airports with babies

[ArthurlovesRosie150517]

We missed our flight at Stansted recently with our 11 month old twins Arthur & Rosie and were left stranded, because of unhelpful unfriendly security staff, which culminated in me being told that there were 'traces of explosives' on the baby food we'd purchased earlier that day. The food was binned, my passport details were taken, I was taken to a room and searched and although I've complained and asked for feedback I've not had any. Anyone else got babies being exposed to 'traces of explosives' on baby food?
Anyone else with babies been told you should be prepared to wait at least two hours in a security queue before your flight?
Should young babies be prioritised like people with disabilities at airports?
What if we needed to change a nappy in the queue packed in with other passengers?
What if our babies needed the bottles of milk and food kept on a tray in a queue for 10-15 minutes?
Why did they throw the baby food away when this is a serious contamination issue for babies?
Grateful to know views of parents travelling with young babies and advice. Thanks.

I thought a lot of airports had family lanes at security? I've definitely been through some with my twins (or maybe I just do a really good daily mail sad face and they took pity on me ). I was travelling on my own with them. I can't remember any security issues but must have got them through some how - I think one of the staff held one. Whilst I don't think people with children are in the same category as disabled people I do think they merit a bit of extra assistance where possible.

There's an ingredient in baby wipes which gives a false reading for explosives apparently, it was probably that.

I agree it's sensible to allow extra time when you're travelling with small children.
