I was thinking about the allergy problem & wondered if your new baby is doing a lot of scratching. Maybe since he has not been in a home environment, his coat & skin are dry and flaky. It seems to me like that would put an excessive amount of dander into the air. Maybe if his coat/skin condition (if poor) were treated that would help. I realize I'm just grasping at straws here but just trying to help. God bless.
