We have bought a couple of the white ones from JL for our imminent arrival. They look gorgeous and the fabric is the quality you would expect. Just be aware, though, by "one size", they actually mean 0-3 months.
I've bought a few of these for my baby due end of January. I just wondered if anyone has any advice on whether it will be too cold to use them then? I still can't get my head around how many clothes a baby should sleep in especially in the newborn phase when they are too small for sleeping bags!
Agree, these are top of my list for best labour saving device in the middle of the night. The number of times I came to my poor ds in the Morning to find his leg poppered up to his midriff was unbelievable.
Can't give you any up-to-date recommendations on where to buy them (ours were from Mothercare and eBay, 8.5 years ago) but just wanted to say that they are so useful. We used them for the twins and during every night nappy change I would be grateful that I wasn't having to negotiate two sets of sleepsuit poppers.
