And it wasn't as bad as I thought it would be. I didn't have to detach a child from each leg and then run, leaving them howling as their mother deserted them (which was worrying me all night). I did leave them howling but the nursery called to say that they had stopped and were starting to settle nicely. When I turned up to pick them up after 2 hours they were both playing quite happily. Adam said that he had cried a lot but then he was alright and Lukey had cried alot too. That was to be expected, they would have cried at any new nursery. I felt quite cheerful about the whole event.
Then I made a mistake and decided to do some research about the effects on pre-school children placed in a nursery which doesn't speak their mother tongue (my aspirations to forward thinking and planning remain firmly in the aspirations phase). Having not really thought too much about the process of young children learning a second language, I had merrily just assumed that it, sort of, just happened. Which it does, sort of, but with a number of other developmental issues attached. One of which stood out from all the others: apparently it is common for a child to go completely silent for a period of time of UP TO A YEAR as they assimilate the new language (link to article here). Needless to say this has freaked me somewhat. More deep breaths and a glass of wine as I assimilate that fact.
In the meantime they are due back in to the nursery again for another 2 hours tomorrow. The staff are doing their best to help the boys settle in. We shall just have to see. One day in it seems to be going ok. Tomorrow, as they say, is another day.
