I have a chunky, wriggling 16 month old (wish I'd thought of a sensory box a year ago, sounds fab
I have recently bought 3 sized LL pockets and would definitely recommend them too. We have lots of LL one size pockets which have been my workhorse nappy for about a year but I can see her chunky thighs won't last much longer in them. The size 2s I've bought will clearly last her for a decent amount more weight gain as couple poppers left on the legs.
I think a lot of people have found opposite to me but I find snaps great for wriggling baby as once I know which which setting she needs I do leg snap on each side first and then waist, so if I have temporarily lost the battle and LO has escaped off the mat i know the nappy won't fall straight off and I can scramble after her to finish it off (as you can see I'm not great at keeping the upper hand here
)... Needless to say I change her on the floor
