LActose intolerant and longahaul flight

[FiveGoMadInDorset]

Sorry posting on here as I know I will get more responses. DS after a bad 7 weeks with c*y HV's and a misdiagnosis just been diagnosed as lactose intolerant, have done a day on Infasoy and the difference is amazing. We are flying longhaul in a couple of weeks, does anyone know if C&G do Infasoy in ready made cartons or any other makes or failing that how best to travel and make up bottles. Thank you in advacne and I apologise if I don't get back to this thread as we are going out soon.

From my experience, baby stuff is usually OK. I would keep it in a carton through security, and ideally, would get a letter from H/V or GP saying DS is lactose intolerant as a response as they will insist you can buy formula in the departure lounge.

Thank you will try and get cartons and a doctors letter.
