Holding onto Toddler shoes ??

My first child is turning 5 early next year and I’m currently pregnant due in a few months, I have some brand new shoes from my 5 yr old from age 1-4 yrs old should I save them for my new baby or donate them and then just get the new baby new ones when it’s time? Lol What do you ladies do I don’t know why I’m confused by this I guess because I’m trying to save money where I can but then will the shoes even be good by then. Also they will have the same birth month. Let me know what you ladies think, thank you kindly!!!
