Ditto everyone else here regarding using a lighter sheet. I swaddled mine (including summer in UK and summer in Sydney) until 8 months when she made it clear she didn't want to be, and think it is the best thing ever.
my dd is nearing 15 wks and I'm pleased to hear that swaddling lasts so long. I wrap her all the time. I found 3 small tablecloths in Bernardo's when I was pg and bought them (50p each) because they were of high quality cotton, great colours with 70's patterns. Possibly from the 70's as they had a lovely 'washed many times softness' to them. I thought - these will come in handy one day.
Was the best £1.50 I have spent in a l-o-n-g time.
My child birth educator said her son always loved swaddling and even at 12yo, likes to have the covers wrapped tightly around him! Your baby will wriggle/get annoyed with the whole swaddling thing when (if) they don't want to be swaddled any more. Enjoy it while it lasts!
We swaddled in just a sheet when it was warm but I have swaddled 4 children until they are huge eight month lumps and get out of the swaddling five minutes later......we have had four fantstic sleepers and I put it down to that. A west indian midwife taught me as a very naive mum 13 years ago in Liverpool and I never looked back!
thanks all. good to know that would be fine even if ds wants to carry on being swaddled for ages. i really feel it makes a big difference to his sleeping (and that it makes him happy) so would have been very sad to stop.
now on the look out for a piece of muslin big enough to swaddle with.
