DD1 is 4.4 and DD2 is 10 months. I am starting to put away all the toys that DD2 will shove in her mouth as she's starting to move around and I wondering what can I get that both DDs can play with. Bought a massive lot of Brio train stuff the other day. But I was also going to buy a big load of Duplo too - then I saw it says 1.5-5yrs as the age range. I'm sure I was playing with DUPLO way past this age. What do you think? Is 4.4 too old for DUPLO?
