Chicken pox in 10 month old twins?

[Littlegemx]

Hey guys.
I have five kids for reference.

Back at the end November my eldest daughter (aged 5 ) brought home chicken pox from school. She was covered within and day and only worsened for 5days with a temperature that lasted 4 days straight. Her two younger siblings, aged (4& now 3 years old) caught it exactly two weeks after her however they both had it mildly although they still suffered. Now it’s been exactly 2 weeks since the middle two children have had chicken pox and one of my twins currently 10 months actual (8 months corrected, they were born at 30 weeks) now has chicken pox. I stupidly made the mistake of googling chicken pox in babies under one and it’s telling me all about these complications. Twin 2 has a lot of breathing issues and although he hasn’t caught it yet I’m extremely paranoid it’s going to affect his breathing if/when he catches it.
So far twin 1 isnt phased although she’s more clingy and wanting more cuddles and attention.

Can I have some positive stories on how your ex preemies dealt with chicken pox and if they had any complications etc.

Our 30 weeker with asthma and repeat respiratory admissions caught it at 13 months and no complications breathing wise. She had a mild fever and mild cold symptoms the day before it started and the cold continued, but it very mild. I think chickenpox is generally the opposite of normal illnesses where the younger they get it the milder it is.
She got immunity from it, but that's not always the case under/around 12 months so worst case they may get it again some point but they should build at least some immunity even if that happens and not have it as badly as children who get it at 6/7 and are more often coated in them and suffer badly.
