38-year-old Lucy has just discovered that she's pregnant, and she and John are going for a scan.
Baby Jack has arrived, and Lucy and John are in shock.
No sleep, no sex, and now poor old John has got to go back to work.
Still no sleep and no sex.
So Lucy couldn't possibly be pregnant again.
Baby Rosie has arrived, and with her, the joy of shopping with a double buggy.
Then John springs a surprise.
Rosie is two, and Jack's about to go to school.
Could life for Lucy and John be about to return to normal?
