Headhugger for newborn in BJCM double

[BabaandBump]

DC2 due in December and have bought a 2012 BJCM double. DD was 9lbs and out of her carrycot in 6 weeks. A recent growth scan indicates that DS will be bigger again (I realise they aren't that accurate through!) and money is tight so would rather not pay out for a carrycot that may not even last a month!

Can anyone recommend a headhugger or caccoon that would suit a newborn in the BJCM? We already have a BJCM footmuff which I was thinking we could use with a headhugger.

Thanks

My sister used a Summer Infant snuzzler- think that's the name! Not in BJCM, in a M&P pliko. It's universal though. It was very soft and baby laid on it and straps did up around it. HTH

Thanks Milkybrew, that's really helpful.
