See if the Panadol helps. Did the nurse give you a list of common reactions for the needles he had? I didn't give Mackenzie any panadol before her needles although it was suggested by other mums to me and I asked our nurse what she thought and she asked me if I would take medication in anticipation of not feeling well? Good point I thought and could always give Mackenzie something after her needles if I felt she needed it (luckily our nurse was the best in the world - no bruises, bumps or any reactions - she is VERY in tune with babies). Also with Mackenzie's 6 and 12 month needles she suggested to have a drink (like ribena) to give her straight after her needles - I can't remember why - something to do with helping her levels of something which can go down after having needles - I'll check with my mum she'll remember. Good luck with Kynan and go with your gut instinct if you feel a trip back to the Doctor is what he needs then do it or if you feel he just needs lots of cuddles do that. I'll get back to you on the drink thing so you can be ready for the next round!
