Oh, hun, so sorry you had this big scare. And poor lo too.
Im glad the allergy its been managed. Was this the first time you gave him egg? Was it whole or just the yolk? Here its recommended to give first tiny bit of the yolk, if that`s ok you move on to give 1/8 then 1/4 then 1/2 then the whole yolk and the white part of the you give after one year.
My lo has lactose intolerance. That`s why we have so many issues. I remember when I took her to the doctors when she was 3weeks old. I held her at least 6h straight. I`d put her down for the doctors to check her up but then pick her up immediately. My mum kept asking to hold her, but I just couldnt let go, I knew if I did I`d fell apart.
And now, while on vacation I didnt hear her crying after bt. When I got to her she was very upset, I felt so bad I didnt wanted to put her down, even when she was calmed down and almost asleep. So I moved the cot in the living room, where I could see and hear her all the time, and I slept there with her.
So I understand the need to to sleep in his room very well. I hope that the lo dosnt have bad side effects form the meds. I do know about dexamethasone. Can you maybe ask if your doctor is ok with you giving him B6, that`s what our doctor suggested so that lo can get some rest from all the crying.
I hope you both get some rest now. Let me know how things are going.
