My 7 month old DD keeps choking on her saliva.... I don't mean choking as in turning blue... Just coughs face turns red eyes get watery. She doesn't seem phased by it but it has me concerned a little. She started drooling like crazy at like 2 months old and that's when I started. I have mentioned it to her pedi at every well visit and they say its normal. I thought tho, by 7 mos old this would have passed already. Do any of your LOs do this???
