I'm gathering idea's for gifts for my own boys who will be 2 in August and 4 in February with Christmas in between.
The first two I have 'stolen/borrowed' these idea's for gifts for my own boys from the blog Two Straight Lines.
Kids sized gardening tools (available from Big W)
Butterfly nets ( still looking for these)
A larger slide than the 2 ft high one we have ( haven't looked for this yet)
A set of soccer goals that are moveable and we can pack away ( nor this)
Build a sandpit. I like this one from Ohdeedoh
There were more I know.... but I can't think of them right now
