When the baby girl was born my mum gave me the beautiful blanket that my aunt knitted for me when I was a baby. After just a few months, alas, we had to stop using it – the baby girl is such an active sleeper that she ends up at the other end of the cot from where you put her, kicking off blankets and wriggling out of pyjamas in the process. Fortunately we had a hand-me-down baby sleeping bag given to us by a friend, and have since amassed quite the collection of them, turning to eBay each time we need the next size up or a different tog rating.
The primary benefit of the baby sleeping bag is that it keeps your little one warm (the Gro Company has a helpful guide to tog ratings and what your baby should be wearing underneath her sleeping bag), but it’s handy in other respects too. Zipping the baby girl into her sleeping bag is an important part of the bedtime and nap routine, working as an effective sleep cue whether she’s at home in her own bed, at nursery, or out adventuring with us. The baby girl is a pretty good sleeper when we’re travelling, which is probably as much to do with luck as anything else, but the presence of familiar objects like her sleeping bag surely can’t hurt.
The most practical baby sleeping bags, I’ve found, are those designed with travel in mind – they have a two-way zip plus a slot at the back so you can use them with a car seat or five-point harness. This means you can dress your baby in her pyjamas and sleeping bag when travelling at night, put her to bed in her car seat or pushchair, then transfer her to her cot when you reach your destination, without messing around with other layers. We do this on journeys, but also on holiday, doing the standard bedtime routine before heading out to a restaurant with the baby girl all wrapped up in her pushchair. I prefer this style for use at home as well – it’s easier to get the baby girl in and out of a sleeping bag with a zip down the front than it is the standard ones that do up at the side.
A sleeping bag is more convenient than a blanket on planes and trains too, or indeed in any potentially chilly environment where you might have your baby napping in your arms or on your lap. You can even put it on over a sling, though you probably won’t be able to zip it up.
