Hopes of the End (Loki and Thor) (Childcare AU!)

(!Infinity war spoilers!)(My own AU) In the final battle, after the remaining heroes bring back their loved ones. Thanos used the Time Stone to turn Thor back into a small child, attempting to fight the God at his weakest. After a thrashing by Loki, the Time Stone was shattered, causing Thanos to flee. Though Loki has no idea about raising a child, with Tony Stark and Doctor Strange's help, the duo attempt to rekindle what brotherly love they had, whilst finding a solution to Thor's situation.
