My DS has been given a sum of money from grandparents, it’s about £10k but could end up being more next year as FIL is selling property and wants to give some to GDCs. I’m confused about the best place to put this? Are ISAs pointless as he’s a child? We don’t want to access the money obviously but would like the option to move it around to get the best interest rate if possible so again I’m not keen on an ISA that locks it down until he’s 18. Can anyone tell me what they’ve done? He is only 5 months old currently.
