Jackson hasnt slept through since 8 months, I put him in a growbag two nights ago, and he has slept without a peep until 8am both nights! I got mine from David Jones, they are living textiles brand and only $39.95. I prefer to buy these type as opposed to the Kmart etc. ones becuase they are much warmer and rated according to togs. Jackson sleeps in the 2.5 tog in flanelette PJ's with a singlet and no socks, and a light blanket over the top (gets to about 8-10 degrees in our house at night) I am going to get him a 1.0 tog for the warmer nights. Dee I got Jackson the 18-36mnth bag because I knew he would only last the size down a few months, and he is fine in the larger size, he isn't as big as Matthew, so for Matthew it would be fine.
