I currently have a very sleepy bub on me

She had her needles this morning and has just wanted to sleep since with little feeds to calm her down as she wakes screaming like she is remembering the incident. So sad.
Did your bub get a temp and was it later that day? She doesn't seem to have one yet, but can't be sure as she is glued to me.
Should I just give her a dose before we go to bed tonight?
