My 3 month old ds is v.snuffly especially at night. I think it is allergies rather than a cold as he has no other symptoms of a cold and his dad is a walking, talking allergic reaction! He used to sleep for 6 hours but now wakes x 2 and has difficulty feeding. I have tried using a vapouriser, one of those gross suck the snot out contraptions, elevating his cot head and saline drops but there has only been a small improvement - any more ideas?
