LO has almost grown out of his 6-18 month sleeping bags as he is a very long baby. He wiggles round loads in the night too, so I want him to be comfortable moving his little legs around. My question is - what comes next after a 6-18 month sleeping bag? Do you go for an 18 month + sleeping bag or something else? I feel as confused as I did when he was newborn! He has got a little while yet before they get too small, I'm just wanting to plan ahead - so what do you / have you / will you do?
