My 20mths daughter just started PG on 2nd Jan. School has been calling me almost everyday to say that my daughter is crying and is there anyone to fetch her home coz her temperature is higher like 37.8 or 37.9. The problem its been happening too often, me having to fetch her early due to this. When shes back home, shes back to normal, no fever etc. I assume that prolly shes been crying so her temp went up in school. Up to date she has missed 4 days of sch due to this. I am stressed out coz i will be starting work next Monday onwards and i wouldnt be able to fetch her home as and when the school calls. Is this a normal thing for sch to call every now and then and inquire if i could fetch her home? I enrolled for full daycare PG. Please share some advises, any of you. I am very worried as i will be starting work nxt mon. Thank you.
