DD2 just turned 2. A few weeks ago (July 26-31) she ran a high fever. It appeared on the 26th and ran around 102-103, and the evening of the 27th it broke and she ate dinner after two days of nonstop nursing. I assumed she was better, and we went ahead on a trip to see family the next day. Her fever came back during the car ride so we ended up out of state on the morning of day 4 of a fever. I called our regular peds office, spoke with a nurse, and brought her in to see a ped that afternoon. He checked her ears and throat, saw no signs of an infection, and said it was probably a virus. He encouraged us to bring her to their after hours clinic if it got worse. The fever generally peaked at night and faded in the morning, which sort of confused us in the midst of it, though in hindsight it's pretty clear what was happening. She finally ate dinner again Saturday evening the 30th (though she ran a fever that whole night), she ate 3 meals on the 31st, and went fever free that night. She's been fever free since.
The next week she was fussy and clingy. She cried during her beloved swim lessons. She wanted to sit in my lap or DH's during meals. She mostly napped in arms latched on. She also complained that her back hurt. Her back looked fine. DH has back issues and will often say that his back hurts. DD2 will say "my knee hurts" any time she sees a trace reminder of an ancient skinned knee. Despite the clinginess, she was back to her regular active self - running, climbing, jumping, dancing, spinning, etc. I called and spoke to a nurse at our regular ped about it, who didn't feel like I needed to bring her in unless I wanted to. I didn't.
Since then she's been very much herself. She finished up swim lessons full of excitement and smiles. She just started dance class. She eats well. She sleeps pretty well, some typical night nursing, especially as she cut a tooth in that time, but nothing concerning. She naps well, on her own in bed after I nurse her down. She's independent, highly verbal, and very active.
She is very very tiny, 31 in and about 21lbs. I'm only 4ft 10 and finally back down to 115 lbs, and my mother is 4ft 11 and maybe 100lbs, and DH is 5ft 10 and about 130lbs, so it's no surprise she's small. I was worried about the weight loss from the days not eating, but otherwise unconcerned. We did a 2 year well check up last week and the ped was unconcerned about her. I didn't think to mention her back. She has said "my back hurts" here and there since the fever, but she hasn't seemed to be in pain, and has moved on very quickly. I assumed it was just this thing she says...
This morning I noticed a small bruise on her spine. The bruise doesn't look bad, pretty faded and small, but seeing it scared me. She does not bruise easily, and has no other bruises on her body (though she does have a skinned knee). She is very active, and I can think of about 10 things that MAY have cause the bruise (backing hard into a wall, rolling around with her sister, sitting down hard in her carseat and hitting the buckle, lying down on the floor of the van on an umbrella for a diaper change....), but nothing stands out.
Now I'm trying to decide if I should bring her in, or just watch the bruise and wait. What would you do?
