3rd covid19 scare with toddler and I have a newborn!!!

Hi ladies so I just lost my dad a few days to covid19 a few days later his gf died we had a scare because we initially thought he gave it to my son who is 3 years old we panicked as I just came out the hospital with my newborn who is now 3 weeks old, my husband immediately isolated with my son

Everything was fine iv been stressing with my family to stay away from my home like please let us live I'm so scared and paranoid I don't know what to do

I'm out here trying to survive

My sis is my next door neighbor and her kid keeps calling my kid to come and play well they went out to get birthday cake without my consent both wearing masks however and I sanitized my son as soon as he got home also changed his clothes I was furious because this is negligence 😠

My son 2 days later has a runny nose and sneezing alot but that's it he was fine the day before

We are heading into our spring as well

However I'm pushing him away because of fear for our new born baby as well and I feel like a shit mother

Anyone's toddler had symptoms that started like this

Am I being paranoid any moms who feel this way everyday the anxiety 😕
