hello!! this is all new to me so apologies if this has been discussed before... my twins are 2 and have just been moved from cots to beds... and for the last 3 weeks they have taken 3-4 hrs to settle down and go to sleep!! they also have this terrible desire to be naked at all times at the moment and have frequently found them asleepon the floor naked and the room has been trashed!!! help!! any advice... should i split them up or persevere!!Thanks
