DD is 2.5 and she and I have been bed-sharing on and off for the past year or so. She started waking a lot overnight, so I brought her into bed with me. Then my husband has been traveling a ton for his job over the last 6 months and it was easier for me to put her down for the night in my bed. About a month ago we got her out of our bed and into a queen bed in her own room, so I lay in there with her if she falls asleep overnight and come back into my bed.
Well, since then she's been getting sick. She had a small cold, and now she has tonsillitis. I think she's also working on all 4 2-year molars, so that could be it. But I'm also wondering if she's missing out on something by sleeping separately. I can't seem to find anything on Dr. Google. Do any of you have any evidence, either studies or your own personal experience, that shows kids who bed-share or co-sleep have a stronger immune system? I just thought maybe there was some correlation.
