DD is 13 months, not yet walking but loves crawling around, hide-and-seek, peek-a-boo, so I want to get her a tunnel, primarily for indoor use. Found 2 that I like and would like to know if people have used/got on with either. It's either the 'First Pop Up set' from ELC (with tent) or second hand Little Tikes tunnel with solid blue bottom and red mesh on top. I'd get the 2nd hand one for the cost but concerned it'd be too long to be practical indoors!?
