Baby congestion.

Hi

For almost a month. Has been feeding well and wet diapers but can’t get this congestion over with. I use the nose frida and saline drops but still is congested multiple times a day. I believe due to the AC being on all the time.

Should I take her to the doctor or will they be no help?

Also, is it bad to use saline drops multiple times a day all week and the nose frida constantly? Thanks!
