Newborn with cold

So my 4 week old has a cold, caught it from my 2 year old who goes to daycare. She has a lot of boogers and slept terribly last night. I’ve been using the nosefrida to suck out her boogers and am using saline drops. Will use a humidifier in the room tonight. Any other advice for colds at this age? I know you can’t really give any medicine. She doesn’t have a fever so I’m not sure whether to bother calling the pediatrician at this point. She sees her doctor on Monday for her 1 month visit anyway… not sure what else to do to help her get some rest. She’s only sleeping about an hour at a time. Thanks.
