I have just bought a footmuff to go with my Loola, the bebeonfort teknik one. But have just looked for reviews and I see the Boots website has it listed as only being suitable up to 6 months. I was hoping to be able to use it for the life of the pushchair! DS is 9 months now so by the time we get some colder weather and I want to use it, will it be pointless? I can probably still take it back so just hoped someone would be able to let me know before I open the packaging.
