Luey, dh has mostly used the Pikkolo, since I'm about to pop - which means the Pikkolo would be done up under my belly and Riv doesn't like being carried so low - I've stuck to the Mei Tai done up above my belly - if I babywear at all, too hot and don't go anywhere anyway these days!
Dh really likes the Pikkolo (once again, not in the heat though). Riv really likes being carried in it, especially when he's tired and we're out/making dinner - he can see what we're doing and feels involved!
I'll keep you posted as the baby is born and I fit some more babywearing in without my belly.
