I just took DS in for his 4 month vaccinations last Thursday. He was a bit cranky and then very sleepy that day, sleepy the next day and then after that (Saturday) onwards he's being a terror to get to have any nap at all. Once he wakes up for the day he may only have a couple of cat naps totalling half an hour in the ten hours he's up for the day.
The funny thing is that he was exactly this way for about three or four weeks after his last immunisations. And the timeline of how it started is exactly the same. I had put it down to a huge wonder week / period, and he did go up from the 25th to the 50th percentile in that time but now it's happening again I'm wondering...
Is it just a huge coincidence that his growth spurts are starting right after his immunisations or could it be a side effect from the vaccines? Has anyone else had their bub do something similar?
Please don't turn this into a vac / anti-vac discussion, I just want to know if this is common.
