Do you have a source? Would love to learn more. We have a child that’s 8 months old in a similar situation. Need to prepare.
For data, you might look at RSV trends compared to usual. (Usual is winter spike).
The best thing for your child is for them to socialise as much as possible with other kids. That means they will get sick. In normal times, 2-3% of babies end up in hospital with respiratory infections at some point. Obviously in the short run it sucks, but long run it's healthy.
