DS1's MC Tobi straps have just jammed we can't move them at all, we had the same problem before and we sent 1st one back after about 5 months and it was replaced. However this one has lasted somewhat longer say 14 months and I am now worried that this may be a known problem?!?!? Has anyone on here had similar problems? My main worry is that 1. we are going to have to buy a new one for him now as we are outside the 12 months, and 2. before this happened we had just bought one for DS2 also so it may happen with his too! Thankfully this morning we managed to resolve the issue by putting DS2 in to his rear facing carseat which he JUST fits in so we could get to work and child care safely but what if this isn't an option! What would I do then? Any help would be appreciated!
