hi myboys.. not sure if this would help you but my boy is 13 months, he is my only one but i am 3 mths pregnant with my 2nd.. my little boy is so so busy all day and i was going through the same thing.. morning sleep was not a problem, but arvo sleep and night time was so hard, i was finding myself in his room at night for over 45 mins and resulted in etting him control cry in the end which broke my heart..so i spoke to my clinic nurse to see if she had any ideas... she told me to try this routine:
5.30pm dinner
6.30pm bath
7.30pm sleep time, with sleep time i place one hand on his shoulder and the other patting his bumb.. i have done this for 2 nights now.. 1st night took 30 mins to put him down, the next night 20 mins
5-6am.. bottle
8.30-9.00am breakfast
11.30am sleep

she said that cause i was having problems putting him to sleep in the arvo maybe 1 sleep but a big one woould be an idea... i have done this for 2 days now and last night he sleep from 8pm - 5am all night where i was having him sleeping from 10pm to 5am with 4 wake ups so i am very happy with his progress...
just thought i would share this with you but not sure if it would work for you, just an idea and to she with you my experience...

good luck sweety... hope it works out fo you xxx
