My 17 day baby is a little sick ๐Ÿ˜“๐Ÿ˜ข

I tried so hard to take care of him n he ended up getting a bit sick. His sister was sick now he got sick. So much for Lysol n hand sanitizer n all that ๐Ÿ˜ข๐Ÿ˜“ He has a little mucus in his nose. Any advice on how to make them feel better? I have been using the nose pump but I want to know what else I can do for him so he can feel better ๐Ÿ˜ญ๐Ÿ˜“๐Ÿ˜ข thanks in advance mommies๐Ÿ™๐Ÿผ๐Ÿ’•
