DS is now 21 weeks and weighs too much for me to carry on using the sling to sleep in. The trouble is it's the only place he will have a decent sleep, anywhere else he'll drop off eventually but only sleep for 1/2 an hour. I can get away with this for a couple of naps each day but if he doesn't get a long sleep at some point he ends up just having a total overtired meltdown.
He has no problem sleeping in a cot overnight and used to have long naps in the pram so I'm not sure why these days he has to be in the sling.
I would love to carry on with the sling sleeps but my back can't take it much longer... please help!
