Hi Ella,

DS was in a sleeping bag from around 5 months. Before that he really like to be wrapped, but once he started writhing around trying to free his arms I would wrap him with both arms out (he didnt like them in there anyway so I didnt see the poiint doing one at a time) and then put him in a bag after that.

It did take a few days for him to get use to it, becuase we wrapped reasonable snugly in comparison to a bag, so I had my mum in my ear saying 'ooh see he doesnt like it' blah balh. After a couple of days he was fine, and he stayed sleeping in a sleeping bag until close to 2 years old.

As for tog ratings, it depends on the temperature inside the babys room, and what else he is wearing to bed

If you google grobag their site has a section on what tog for what temperateure. There are a lot of other good brands that are up to 50% cheaper than them. I have used 3 or 4 different brands of sleeping bags and they have all been fine.

The thing to look for is that they are sleeveless and generally not made from fleece.

2.5 tog bags will generally be high fire danger - this is the same with bedding of the same/simlar rating - you need to keep in mind that the bag is bedding not pjs. What evr the bub wears underneath should be low fire danger.
