tumbles been meaning to write all day. I can understand your feelings regarding your ds1' English getting worse, or rather his German getting stronger. And I think it is very good that you insist English being spoken in your house. But his German eventually being his stronger language is inevitable really, as you live in Germany, his friends are German, he's at a German kiga etc. that doesn't mean he'll lose his English though.
Just as an example, my ds1 spoke much better English than German until he started kiga at 4. Since then his German has become his stronger language. And he often can't find the English word fast enough when he talks to me. Rather than 'stammering' like your ds1' my ds1 simply uses the German word. I then simply help him along and repeat the German word in English. I wouldn't worry about his stammer just yet!
Also I was amazed at how well my ds1 can speak English - without any German words - when he has too. The friends in Wales we are visiting this summer, came to visit us a year ago. Ds1didn't speak any Germish at all when speaking to them - I guess because he knew they wouldn't understand. And with me he chooses the lazy way, as he knows I'll understand him anyway.
What I am trying to say with all my rambling is, I wouldn't worry about his English. It may not become his strong language - unless he ends up living in the UK - but it will always be his mother tongue.
antique your description of your ds made me 
nutella I hope you feel better soon!!
admylin how is your neck now? About 6 months ago I had a really painfully stiff neck several times within a few weeks. Once it was so bad I had to go to the out of hours doc. He gave me painkillers but they didn't even touch the pain. I hope you've been prescribed something that works!
linzer and mrtumbles your dd's text messages make me 
Ds1 has been better at home these last few days, but he's had terrible days at kiga
. I'm having one of my 'shall we try medication or not' moments. I know that if we choose to give medication a go, it will take several months to find the right medication and the right dosage. And I am wondering if we may o him a favour trying it. I am worried that he will be seen as the naughty child straight away by his classmates, that he won't have a chance to make friends, perform to his ability etc. I just do t know. A year ago I already had blood tests done for him in preparation for medications, but then chose to wait a little longer. It's such a difficult decision as they are such strong stuff. On the other hand, I have heard very good reports about it both from patents as well as children. Actually just the other day I spoke to a neighbor. It turns out her son has ADHD, and they started medication in the summer. She wants to get away from it long term, but says that for the first time in hs life ( he s 9) he sent an outsider anymore at home and he now has friends at school. Sorry, more rambling, I'm terrible 
Hope everyone has a good weekend and poorly ones are feeling better very soon. We have ds1' birthday party tomorrow. But I've asked both of our babysitters to come, so hopefully everything should be under control
