Well, perhaps we should just calm down a bit.
1. According to all reliable sources during the past few years, the Queen is in ''remarkable'' god health for her age (yes that's the word they have been using), and if you take a look at her when she is out and about, you'll se it.
2. She has been spending her weekend with Philip in Norfolk, following her busy schedule in Scotland last week, and is on her way back to London today for yet a busy schedule this week.

The Queen and the Duke of Edinburgh will not be attending today's christening. There's no health issue for the Queen. She was working flat out in Scotland last week and has got a busy few days in London with the RAF Centenary event tomorrow and #Trump on Friday.

The Queen & Philip have just spent the weekend together in Norfolk. He is remaining there while she travels back to London today. Her decision not to attend was mutually agreed with William & Kate, while Philip clearly doesn't want to attend public events unless he really has to.
