Leroy having fever

Hus needs to work today so I bring Lervin to my mum's place.
As usual he is always very excited when I told him we are going to mum's place.
He brought along his Thomas sling bag. In his bag he put Thomas storybook and Thomas bubble gun.
Leroy is having slight fever around 37c. I guess it is due to MMR jab. It mentioned fever might surface after 5-12days.
Worse is he is coughing, have runny nose and pleghm. Poor boy. Hope he recover soon !
