7mo bb pooop after 3days from his NCIS vaccination

Wah, I totally understand the worry, yellow seedless mushy poop is actually a reassuring sign that things are not too off, but the sudden jump in frequency after the jabs is definitely something to keep an eye on. From what I've heard around, reactions after the 4-in-1 and Pneumococcal combo can actually go either way, some babies poop much less than usual for a few days, while others like your little one seem to go the opposite direction with more frequent stools. Someone in my mum group mentioned their baby had similar increased frequency for about 3 to 5 days post-vaccination before settling back to normal, so it may just be the body adjusting. That said, since it has already been 3 days and the frequency is still worrying you, it is really worth a quick call or visit to your PD just to rule out anything else going on, better to get a proper check than to second-guess yourself!

Aw don't worry too much, frequent yellow mushy poop after the 4-in-1 and Pneumococcal jabs is actually a known side effect, and someone in my mum group mentioned their baby had the same thing around day 3 post-jab, it settled on its own within a day or two. The yellow seedless texture you described sounds like it's still within normal range, so that part is reassuring, but I won't sugarcoat it, the frequency can be really draining and stressful to manage, especially with diaper rash risk piling on. Just watch out for other signs like fever, vomiting, or if your baby seems unusually lethargic, because those can also tag along with these jabs. Honestly though, since it's been 3 days and the frequency is still worrying you, I'd just bring it up with your PD directly, better to get a proper check than to second-guess yourself on this one.
