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.
