Well we had a breakthrough with the sleep. I did a couple of things all at the same time so not really sure which one helped.

I have put DS back into my bed day and night for sleeps. Feed to sleep lying next to him and no grobag, just put a doona on the bottom of his legs. Everyday his sleep has been getting better and yesterday he had 2 x 2 hour sleeps. Hasn't done that since around 4 months which I think is when I started putting him in the grobag. I am gradually going to try to put him back into his cot for day sleeps without grobag and put a little cot quilt on him.

I hope all you girls are getting a bit more sleep with your little ones.
