I'm happy that you have asked me to assist you with your child and hope that you can benefit from my many years of helping parents like you.
I understand your concern, especially as Dad and having both your wife and baby sick.
As long as she is not running fever, is able to eat ok, and is breathing normally then you can continue to watch her. If she starts running fever or cannot eat due to breathing rapidly or no appetite then you need to take her in.
In the meantime, since there are no medications for colds in babies her age, just keep her nose suctioned out and prop the head of her bed up or let her sleep in a car or infant seat when she sleeps. A cool mist humidifier is very helpful too to keep her mucous from becoming thick.
I see you are offline still but I will watch for your return to chat with any questions.
I have already given a rating of "Excellent Service" your answer was what I was looking for.
