are quite a decent combo. Got fed up with the bugaboo newborn cocoon as to put baby in you have to strap them so every time I breastfed her asleep she woke up with the bloody straps., they do seem to get caught under the baby rather than at the side like most buggies. You have to do them up or the cocoon can slide out as it has slits rather than holes for the straps, unlike a liner. The trick is to do the straps up under the carry handles under the cocoon. It's also flatter and snuggly and my dd still fits at 4 months, wish I'd tried it sooner. Also can stick her in it easily round the house to sleep without straps and lift it out to carry her up steps to the flat.
If I had more £ I'd go further and put a quinny carrycot on with maxi-cosi adapters for a few months.
