almost 10mo female.
july 3rd, 9am. she had a vey small amount of peanut butter for the first time, was perfect all day.

july 4th 8:15am she woke up with 6 hives on her face (pic 1), we thought maybe she had gotten bitten by a bug in her sleep & thought weird but she doesnt seem bothered so we decided to just watch them and went about our day & within a hour of her playing, they were fully gone. around 10:30 we laid down for her first nap (she is nursed to sleep most the time, & we cosleep, including this nap) , 20 minutes in, she started to get fussy & wiggly so i switched sides thinking shes just uncomfortable about 10 minutes later she had a large hive on her forehead & wouldnt go back to sleep. i got her up & gave her a full body check (from this point on she is only in a diaper, no clothes) & discovered she had huge hives on her face, chest, and whole diaper area, (pic 2) still didnt seem super bothered by them & was still relatively happy, i on the other hand was freaking out because they were getting much worse very fast, i called our hospitals ER & they said to bring her in. she cried the whole time there was anyone in the room she didnt know, which seemed to make the hives worse (pic 3) the doctor who was in the room for all of 5 minutes said it was a peanut allergy but the nurse who was in the room for much longer said she wasnt sure about the peanuts as they usually present differently. they did nothing for us at the time but wrote her a prescription for 2.5ml of prednisolone. on the way home her hives started to go away, so we laid down for another nap (stripped the bed & moved locations just to be safe, still nursed & coslept) and again within 20 minutes i could tell she was getting uncomfortable & fussy, she is a very hot sleeper, as is her father, & when i switched sides the hives had come back only on the side she was laying on. we got back up & let her play some more & within a hour & a half they were fully gone again. by 6pm she was exhausted, having only slept a hour the whole day so we laid down for bed (clean sheets & pillows, same bed as beginning) once again within 20 minutes she was broke out in hives again, we decided to give her the prednisolone since she couldnt sleep more than 20 min anyway & they cleared up & around 10pm, her father rocked her to sleep & we had a rough but overall okay night of sleep.

july 5th, woke up fine, no hives, gave prednisolone around 9am, first nap was 1 1/2 hour, woke up with one hive on chin that went away quickly. this is where we're at now. avoiding peanuts just to be safe but confused

worried the hives will come back once we finish the 5 days of prednisolone if it was not the peanut butter. we will be making an appointment with her ped, they were not open this weekend.

so my questions are

1. wouldnt the peanut butter have caused a reaction the day she ate it?
2. the other other change would have been moving a fan closer to her, because she is a hot sleeper, i thought it would make her more comfortable, could it be that?

feel free to ask anymore questions, i tried to give as much detail as i could, tia
