First colds T^T

My baby girl is only 10 weeks old and she has colds for the first time. Her nose is very congested. We went to her pedia yesterday and I was advised to clean her nose with salinase drops and cotton buds, she also prescribed Disudrin oral drops. I also ordered Nosefrida snotsucker which will arrive (hopefully) on Monday. But is there anything else I can do to quickly relieve my daughter of colds? I feel bad. ㅠ ㅠ
