Hi everyone! My daughter is 4 months. And got her shots late due to no transportation. I only took her out before her shots if it was needed. She had just got her ears pierced, but lately she's been cranky. Last night, was the worst night and I even cried with her. She sleeps throughout the night but on the other hand, she turned a little pale in the face, her nose is stuffy (a little) she was crying for a good hour, and sweating all down her face through her clothes. Can she just be getting sick? She has an appt today, but I still want to know if anyone has experienced this....
