13 week old not himself after immunisations and green poo...link?

[BlueCrane]

My ebf 13 week old has just had his second round of jabs on Wednesday. He didn't seem to have any side effects to his jabs at 8 weeks but this time he just doesn't seem himself...been doing some shorter feeds and sleeping more in the day plus seems quite crotchety...then today he's seemed quite distressed and arching his back and screaming a lot, and now a smaller bowel movement than usual which was green! Any thoughts?

Green poo can be a sign of too much sugar - which can be a result of shorter feeds (lots of foremilk not much hind) although ds2 had green poo when he had an long infection.

If it continues it would be worth seeking medical advice of course, and if you end up feeling it might be an adverse reaction you can self report it

Hope he's better soon.

Thanks saintly he's done another small poo but more normal looking and has done a more normal length feed. I've tried giving him a small dose of calpol and he seems to have chilled out so will see how he goes tonight and call docs tomorrow if he still doesn't seem right.

Aww hope he sleeps well and is back to normal tomorrow.

Slept v well last night, all smiles and happy again today and a nice normal poo too! Think it must've just been a delayed reaction to the immunisations or just having an off day! Thanks for your replies!
