Just my luck

So I just had a baby 5 days ago 🤩🥰

He’s perfectly healthy born a lil early 38 weeks but he is super healthy 🥰

I’m having a hard time keeping my 3 almost 4 year old away from him tho she literally started having a cough and runny nose 3 days ago we took her to the doc and they said it’s allergies they suggested she stay away from baby we been trying to do that and make her wash and sanitize her hands every time kinda hard tho when ur toddler coughs everywhere even tho she knows to cover her mouth but what can I expect she’s 3 😰 uh now my throat is starting to feel a lil pain when I swallow 🥵🥵I cant get sick what should I do ????? I don’t wanna get my newborn sick any suggestions??
