4 month shots

Mary

My lo is 4.5 months, she had her 4 month shots 2 days ago. Last night low grade fever and super irritable. Crying uncontrollably, the whole 9.

Can shots make them eat less too? Cuz she is eating way less than before the shots. No vomiting or diarrhea and no fever today either. She is just eating alot less and would rather play with the nipple too.

I just want some normality back here! Help!
