My advice is to give your child the same first name as yours. In that way you can share status (albeit against the program rules) while still alive. For frequent family travelers, parent could go for high status in Star Alliance and SPG, child for One World and Hyatt. Only downside is that you can’t travel together

After death, the child can just pick up where their parent left off. And if they too named their child with the same name, we could have some 150 year old platinums out there
