The Paw Patrol tower is £90, 6 vehicles at £15 each, there's another £90, as that's you at £180 and not got much variety. Add something for outside, playhouse, trampoline, or bike that could be another £200, and on some books, art stuff, a couple of DVDs, box of duplo, games and you could easily blow another £100
If my dc got a bike for Christmas, they certainly wouldn't be getting a toy costing nearly £100 as well.
My dd got a bike one year...I think I added a few books, pjs and her stocking as well. Not hundreds of pounds of toys on top of it.
I think too many gifts becomes overwhelming and they end up not really enjoying them...it just becomes an exercise in unwrapping
