my baby recently seem to have block nose kinda gluey..i sprayed sterimar daily and used the pigeon suction thingy..managed to get out the mucus..but it will eventually come back again. she is still active and feeding well. should i be worried? will it self heal or is there any other remedy that i should try? i can hear her block nose with mucus sound whenever she tries to suckle...other than that, shes breathing normally.
