If she is that congested, she needs that extra comfort that only mommy or daddy can bring. She needs to sleep with you and be next to you. How old is she?? Have you tried putting her upright on a wedge pillow etc. or elevating her mattress?? But....yes, you should keep doing whatever makes her feel better until she is better. Don't make her cry it out--she will only get more upset and more congested. Give her extra love and attention. She needs to be held the most right now.GL
