My 10 month old son was sleep trained at 6 months, we did controlled crying and he took to it so well, within 3 days i could put him down in his crib and he would fall asleep within minutes. Once he was able to stand up this all went to pieces. Since then myself and partner have been rocking him to sleep. He naps well in the day and falls asleep within 20-30 minutes at night but he wakes so much throughout the night. He eats a lot through the day and has more than enough of his milk. We are looking at starting the controlled crying method again but am so nervous that it might make him regress. Both of us are like walking zombies. He goes down between 6.30-7pm but is wide awake by 4am with at least 3 wake ups in the night. Any advice or tips would be greatly appreciated.
