My just-turned-3yo loves: Lawnmowers (real and toy) Cars (mainly toy, but will look at real ones to spot the badges) Trains (all) Duplo Sheep His toy kitchen Toy cash registers Going to Tesco Going to the playground Going for a "wee walk" Running round with no pants on Standing on the windowsill with no pants on, yelling "Put some pants on!!" Running away when I try to put pants on him Baking, but only if we make sheep buns (buns covered in marshmallows)
My 3yo loves Lego- particularly Lego batman and Lego city with police cars and fire engines. He likes the fireman Sam fire engines and helicopter. He also likes superhero fancy dress and knights - shield and sword. He has toy dinosaurs and cars. Playdoh is a big hit and there are some good sets for present giving!
My just turned 4 yr old likes trains (Brio, Bigjigs etc), Lego and Duplo, vehicles in general, play doh, bouncy balls, dinosaurs and books (a trip to Waterstones to let him spend a book token was one of the more successful Christmas presents last year)
My DS1 is 3 and loves all things Paw Patrol especially his little quad bike ride on. He spends hours playing with Brio train tracks and also jigsaws. Cars, tractors, diggers, anything Bob the Builder too.
