my 18month old had a pretty nasty flu/virus around 3weeks ago. During the time of the illness she had a temp for 4days and slept LOADS which I know is normal and what she needed. Now however she is still very tired, not lethargic but constantly sucking her thumb and wanting cuddles. She will play but instantly just wants to stop to cuddle up and always looks like she could sleep! I was hoping 3weeks after we would see a slight improvement? Anyone else experienced this?? I just hate seeing her not like herself. No symptoms of illness now just this fatigue
