Jack told Hayley a secret!

While I was at work on Sunday, Hayley and Oliver were out dining at TGI Friday's with our friends Sara and Manny and their son Jack. (Lucky swines!) At one point they were talking about our imminent new arrival when Jack pointed at his Mummy's tummy and said to Hayley "baby".
Hayley turned to Sara. "Sara?"
She turned bright red. It turns out she is pregnant but it's very early days and not even the prospective grandparents know.
It looks like Jack has reached that age were his parents are going to have to watch what they say.
