I'm slighlty confused. My 12 week old is due his injections this coming Thursday. I've just received his appointment card saying his appointment is 12th may (I thought it weird that he hadn't received an appointment yet) the thing is because he was born on a Friday and clinic is a Thursday he will then be a day of 15 weeks at his 12 week injections..? And then due another set in just over a week..? Is this normal practise..? I'm going to call on Monday and ask why has this happened and hope it's some kind of error.
