I've finally got DH to bite the bullet and order our Bee+ this weekend for DC1 due in August. It's coming from John Lewis on a price match promise deal which doesn't include a footmuff. I've ordered one separately but, as baby will be in the cocoon at first (how long for? I'm thinking 4-5 months) do I need to buy the footmuff now? It'll be around Christmas once baby will be out of cocoon so it must need something. What do you recommend?
