Sickness or something else?

Emily • Momma to 2 beautiful girls ❤️ Rylynn Grace Paynter 💜 Gracelynn Rosemarie Paynter 🌈

My daughter has been having red cheeks for the past 2 days. I’ve checked her temperature and it’s 98.5...she isn’t happy, she’s fussy and she wants nothing but to be around me and her father. She isn’t herself and I know something is bothering her. She’s almost 4 months old. I’m a ftm and I don’t know what to do. If she’s sick or what?? Can someone help me out??
