My DD started nursery three days a week at the beginning of Jan at 7.5mo after doing some settling in sessions in December. I was so, so worried about it.
She has settled in so much better than I dared to hope. She greets the staff with a big grin and happily goes off for her breakfast. When I collect her in the evenings she is ecstatic to see me but I think she would prefer it if the room leader could come home with us too!
Just wanted to post to let others know that if you are lucky your baby will enjoy nursery and you will feel confident that they are taking care of them as well as your mum or MIL would.
