Hi wendy
No worries.. I did have the same situation in the past.We moved from England to Usa few years ago . New place, new friends and different culture was a bit overwhelming for me.I was not surprised when my son seemed lost,too. But we got over it. All you need is to give your family some time to adjust to all those changes. Your son needs to feel that no matter where, he is always important and loved by you. He might need more attention now but it will not take forever. Soon he will get used to new situation.
