hey belfie,

my little man is 2yrs now and i only just got one on Lay-by for christmas from big w with the trampoline on the side

If i thought he would have enjoyed it sooner (he hasnt been a big fan of parks) i would have bought one earlier.....BUT also within saying that majority of kids LOVE swings so i think its well worth it

Also as u mentioned better getting it now so eventually they BOTH can get the use out of it, i am thinking that way too myself get it now for DS and when this bubs comes along it will get use too!
