LO has always cried when we put him down for naps, i assumed it would die down as by now he is very used to spending naps in his cot. On good days he'll moan for 5 mins then go down, others he will scream for 30+. Seems to be getting worse if anything. He's down to 1 nap a day so when he's down its usually a nice long one. I find the crying heartbreaking and dont know how to improve it. We did some 'sleep training' at about 5/6 months as he wouldn't sleep without being rocked or fed (15mo now). Our naptime routine is to read a book or two in his room, close the curtains then a quick lullaby and down. He would get frustrated with me rubbing his back if I'm not picking him up. Any ideas? Do i need a longer prenap routine?? Any advice very much appreciated.
