its never to late.
my dd is now 20mnths.
until she was 14mnth, the routine was chaos, she slept when she wanted and where she wanted. (carseat/pram/floor/my bed/ once even layed over my head in my bed)
then at 14mnths we moved and i decorated her room, decided after all the effort i put in enough was enough, put her cot in there,
at 6pm- bath
6.30- get dried, story cuddles and milk.
7pm- we say good night to daddy and ds, and all her mobiles in her room, teddys etc. then in her cot, dummy and her 'fluffy'
the first night she cried for 10mins, i stood outside the door so i could peek through the gap she didnt get up so i waited and im glad i did, as shes never made a fuss since.
Now she sleeps 6.30pm-7-8am ish
naps 9.30-10-11ish
and another after lunch for an hour.
now she will sleep anywhere i go, in the pram, travel cot or a friends toddler bed, aslong as she has fluffy and dummy, we say goodnight to grandmas lampshade and curtain, just the same pattern is whats needed.
i never ever thought it would happen, but it did good luck!
