my turn for an "is this a normal poop?" post 🙄

Olivia's poops are usually fairly loose, even after starting solids at 4 months. today she's had two smaller, firmer, and darker than usual poops. yesterday she tried blueberry for the first time and had a poop later in the day that looked like it was partly a blueberry poop but it was still loose and normal amount. she had a whole jar and usually only eats half a jar at a time (but she really liked it and wanted more) she also had her 6 month shots yesterday. so... is this normal? I have her mangoes this morning bc they usually cause a poop explosion and this is all she was able to get out and did seem a little uncomfortable as she was working on it. is this the blueberries or shots causing this? anything I can do to help her? more mango tomorrow until things get back to normal maybe? picture makes it look a little lighter and redder than it looked in person.
