DD (just gone 3) has been really tired for the past week, she's also quite pale. She's usually full of beans and rarely naps now. However this week she's constantly been sucking her thumb, telling me she's tired and wanting to snuggle on the sofa. She's had two lots of antibiotics in the past two weeks (amoxicillin for a vaginal infection and then fluoxicillin for an infected finger). It's making me wonder if there's still infection somewhere although both look to have cleared up. She's also grown recently so I'm wondering if this is just a growth spurt? If she's not any better this week then I'll get her a GP's appointment but I just wondered if anyone had experienced similar.
