Hi there! Congratulations on the birth of you granddaughter! I bet she is adorable. This is a great place to come for information and support! I'm sure it must be worrisome to have these hemangiomas popping up. It's so stressful when you're trying to figure out what's going on.
If it were me I might look into seeing a specialist before 6 weeks, just because she has so many, just to rule out any possible issues (internal hemangiomas or airway hemangiomas, especially where you mentioned the "choking" and "whining" sounds.) Where do you live? Do you know if there are any specialists in your area? Keep us posted! Let us know how it's going!
