Anyone know of any baby carrier that does this? Will be commuting on train with baby DS soon and after experience with DD would rather avoid using a buggy. Will be sharing drop off and collection with DH (one drops, one picks) and leaving carrier at work nursery so need to be able to store our laptops within the carrier rather than lug along separately. Anyone any ideas? Looks like it might be possible with the little life traveller though that looks inferior to their other carriers. Wondering about any of osprey's carriers but that level of detail doesn't seem to be on websites.
