Shpuld i send my two years old to nursery?

B&F

I have a 3 months old baby at home and a 2 years old toddler

I am struggling to keep my toddler at home but at the same time I’m concerned that if she goes to nursery she will be bringing different viruses home and my baby will be effected at the same time

Really confused and not sure if i should get a nanny to help me or send her to nursery 🫣
