When my baby was 8 months old, I let him to have 曼秀雷敦 if he had 鼻塞. Before you put the 曼秀雷敦 in his nose, please let him to have the 凡士林 first. It let him felt more comfortable. I’m sure that after he smell the 薄荷, he felt very comfortable. However, if your baby is still young, please consult the doctor before you use it.
