I co-sleep and still breastfeeding 15 month old and my partner has only ever slept on the sofa once, and that was because he got drunk on a Christmas works do. She doesnt need to make him sleep on the sofaCan’t have Aaron in her bed as Milo sleeping next to her at 2 is such a must....yet she can go away and leave them all. Bet Aaron will be happy to actually sleep in his own bed for once!
