My son doesn’t have a fever but he cannot stop crying because his legs are just hurting him so much. I feel so bad for him. Last night he could not fall asleep from the pain I had to give him Tylenol and he fell asleep within 20 min. Same thing this morning I went to the bathroom and when I came back my poor baby was crying so hard but with his mouth closed clenching his jaw. ugh you can say I cried with him because I felt so bad. I gave him Tylenol once again because he could not take a nap from the pain in his legs. Any other things I can do for him so that he’s not in so much pain?
