My 7 month old son taylor had his 3rd primary immunisations and pnemaccocal injection last week. Last nite he cut his first tooth. Today after his afternoon nap at around 4 he woke and i fed him his bottle. I noticed he had temperature so i used a temperature indicator on his forehead. It came back showing high temp of 102 f / 39 c. I called doctors as internet says children should not have temp when teething and may be indication of infection or virus. Doc said it may be delayed reaction to imms but that his two children had temperature when they were teething and to keep and eye on him. Well and hour later he wanted to go back to sleep again and now is looking very tired. This is not like him and he hasnt really done much today because weve had workers in the house doing plastering so ive kept him with me upstairs. Is something wrong with him. He bangs his head alot because hes climbing and standind in cot. I always checked on him but Sometimes he doesnt cry to let me know hes awake and will climb and fall and screams so then i hear and come up to find a red mark on head could this have anything to do with it. Is my baby ok?
