Was getting in a proper tizz with DD2 (8weeks). She'd only nap in her sling, with me walking up and down, and occasionally with a dummy. I was getting bad backache and poor DD1 was severely neglected! Finally decided enough was enough and put her in her moses basket in her room. 5 minutes of half hearted crying- and asleep! Properly! For ages! Now all I do is watch for a few yawns, stick her in the cot and that's it. PLEASE TRY IT!!!
