awake at night

is anyone expierencing more night wake ups. my son has been sleeping through the night for months now. lately he will not let me lay him down to sleep. i have tried everything i can think of. is it just a phase? will it past because after being awake at 8:30 until 10:30, then 11 to 12 then 3 until 5 is killing me. i was so frustrated last night i ended up yelling at him to go to sleep. is there any light at the end of this tunnel or am i doomed to sleep train and cry it out.
