From the sight of his beaming smile, I got the feeling poor William had no idea what was about to happen.
The dreaded vaccinations.
It feels strange to have your healthy baby injected with a cocktail of vaccines to kick-start his immune system.
But the scientific evidence is firmly on the side of immunisations, so there was no doubt in our minds he was going to have them.
After all, why wouldn’t we want to give our child the best possible protection against a whole load of horrible diseases?
Having said that, sat in the doctors’ surgery I couldn’t help but feel a tad apprehensive about his first set of jabs.
It didn’t ease my nerves to see a girl bawling her eyes out as she came out of the nurse’s room – and that was the mum.
The baby in her arms was bright red and screaming so loud other patients were desperately trying to shuffle their way to the other side of the room.
It was our turn next.
Two nurses welcomed us with their reassuring smiles – the calm before the storm.
We sat William on his dad’s knee and un-popped his tiny baby grow to expose his little legs.
Then the nurses launched their two pronged attack with one pinning down his legs (not that he was about to make his escape – he could barely hold his own head up, never mind run out of the door!), as the other jabbed each squidgy thigh.
Cue an ear piercing scream and a baby with a face as red as a Brit who’s been cooking in sun tan oil on a Spanish beach for a week. Thankfully, all it took was a huge cuddle and within 30 seconds he’d forgotten all about the ordeal. So it wasn’t that bad after all.
It’s just a shame there’s one more hurdle – ripping the plasters off his legs.
