T.,
Yes, the fever is normal. They playing? I don't know, I don't think so though.
Read your "A little about me" and want to say this: trust your gut instincts. When you get that feeling that you know what's going on but can't explain why you know what you know, just go with it.
19 months ago I had my family doctor, my husband, and most of my friends and family suggesting, in various strengths, that my son needed speech therapy. That little voice/gut instinct resisted. Part of it was my pride, that I was his mom and could do it all for him and I was a failure if I couldn't.
I resisted and resisted and procrastinated. When my daughter was born 19 months ago I took my son out of daycare and we all stayed home. He got some one on one time with Mommy to fix his speech, and now he's fine. For him he just needed the 1:1, not the 10:1 at daycare. He gets lazy in his speech now and then.
Hope this helps, I think I wandered off topic a little.
