Okay, another update: First specialist's technician didn't contact us straight away so started to panic as time is of the essence and asked my peadiatrician to refer me. He did to a very good neurosurgeon at Great Ormond Street who said he didn't use helmets and it will start to sort itself out but there will always be a degree of flatness.
So back to square one.
Then went back to one of the original doctors (Dr Christoph Blecher from Frankfurt)who has a clinic in Harley Street every two weeks and we saw him yesterday evening (Sunday). As we have been reading/researching this for a while and having seen 2 dcotors already, we felt this one was the right doctor. We saw one baby at the clinic who was 9 weeks prem and had lay on one side for nine weeks and had a severely flat head on one side.
Today we went to Kings College in Denmark Hill, London and has the casting done. We saw one baby about to go in for the same and another who had been wearing his helmet for 4 months and his parents were very happy with the results.
This is what I have learnt:
Flat heads don't go away on their own. Boy babies have more of a tendency to develop this as they are usually lazier than girls. It's important to change their sides for sleeping so that they don't sleep on their back only. If the flatness starts, the best time to correct it is in the first year and the earlier in that year the better. The second year is harder as the head grows at a slower rate and also by the time your baby is a toddler, they will have a mind of their own. Nurses and medical staff need educating as Health Visitors, GP's, etc are all telling parents not to worry.
We are going to Frankfurt to have the helmet fitted this weekend to save waiting two weeks for his next visit to London. Shall look up his website and will post it for anybody interested.
