Just came back from two-week holiday on Monday... Was upset they confiscated my UNOPENED jar of Sudocream. It was the medium sized jar.
They seem to be more relaxed now with baby food and liquids otherwise... We had a lot of baby food (we were flying long haul with 18-month-old) and they said we had to choose half of all we brought to TASTE. We had some Ella's Kitchen pouches so those were easy to open to taste and seal again. You are also okay to bring water in a baby bottle (they didn't even bat an eyelid we had a full bottle of water in a toddler drinking cup). We were also fine to bring in those ready-made cartons or bottles of formula milk. We had a sports bag as hand luggage and they were fine with that.
I had to throw away several cartons of juice and bottled water. All liquids had to be less than 100mls, in a sealable bag measuring I think no more than 20cm by 20cm. Couldn't find any juice cartons/bottles this small so ended up paying £6 for 3 small kids drinks on the plane.
