DS had his 16 week vaccinations yesterday morning. He breezed through the last two lots without any effects. Last night he had a bit of a temperature so I gave him calpol and he slept a lot yesterday. Today he’s barely napped whatsoever. He’s had three 20 minute naps. I can tell he’s tired but he just won’t sleep, or he wakes straight away. My breasts are also really full because he hasn’t been feeding as much as normal. He is still having milk and wet nappies just less than normal. He doesn’t seem hungry. Does this sound like a side effect from the vaccines?
