I put my daughter on a schedule right away. You have establish a bedtime routine.
After my daughter has her bottle, she plays, we go for a walk, she gets a bath, eats again and plays in her crib.. Then we put her to bed after 20 minutes. By 4 weeks old, she would sleep from 8:30 pm until 4 am. you just have to be consistent.
Look into the book On Becoming Baby Wise...
Schedule is very important such as bath time, feedings etc. Just like Aubsmomma472014 said. My son was still getting up during the middle of the night when he was 6 mo. old and I eventually did the cry it out method. I wish I would have started routine earlier with him but now I know better for my second. Set a "bed time" where everything is dark and quiet at the same time every night. Good luck dear <3
Like sew2009 said on becoming wise works amazing. I used it with my son and he was sleeping through the night by 12 weeks. He is almost 6 now and still follows the same basic sleep routine. I went out and rebought the book to use again this time around!
What about just following the baby's needs?
My 1st born slept threw the night ever since he was born. I was successful with breastfeeding my 2nd and it was like he was constantly hungry and woke up every hour or 2 to eat , i only breastfed till he was 7 weeks after i started formula he slept threw the night
Both of my kids slept through the night by 2 weeks old and were on a solid schedule at a month. It seems harsh but at night time turn on as little light as possible and don't play with baby at all. I barely said anything at night so the baby would know the difference between play time and sleep time. Not trying to say anyone's parenting is wrong or mine is better but I also wouldn't do play time in the crib so the baby knows the crib means bed time.
