Hey! Stop thinking you are doing something wrong and look at this poll immediately!
https://babywhispererforums.com/index.php?topic=55035.015.4% of babies were sleeping 8 hours+ at 3 months!!!!
Your LO is completely completely normal. I would suggest you lower your expectations a little bit - unless you think those of us who responded to the poll are a bit barmy!
I really would advice you to remain breastfeeding as much as possible if you can as there are clear long term health benefits. The more bottles you add will affect your supply. Bottle fed babies sometimes also have more difficulties with wind even if it is ebm.
Here's another - more official study:
In this study, part of the Avon Longitudinal Study of Pregnancy and Childhood (ALSPAC), researchers surveyed the parents of 640 babies. Some of the results:
Only 16% slept through the night at six months old -- 84% were not sleeping through the night at 6 months
17% woke more than once per night, ranging from twice to eight times
5% woke once every night
9% woke most nights
50% woke occasionally
16% of six-month-olds had no regular sleeping pattern
And another to show things are always going to improve in the way we expect: Scher A. A longitudinal study of night waking in the first year.
Child Care Health Dev 1991 Sep-Oct;17(5):295-302.
Abstract: A longitudinal study of the development of sleep patterns addressed the issue of continuity and change in night waking in the course of the first year. Mothers of 118 infants, who took part in a follow-up study of normal babies, completed a sleep questionnaire at 3, 6, 9 and 12 months. Regular night waking was a common characteristic throughout the first year:
Baby's age % babies waking at night
3 months 46%
6 months 39%
9 months 58%
12 months 55%
What I'm basically saying is that 'yes, it sucks that you are being woken up'. However you are not alone and in the grand scheme of things the fact that your baby is breastfed and nutured is going to mean a lot more. This phase will pass. There are things you can do as the sleep boards will tell you but acceptance of what is normal may also help you to move forward. I'm not sure how much posting you have done on the sleep boards. You are right to mention that the 'baby whisperer' philosophy wouldn't recommend leaving a baby to cry for ten minutes. I know we all get desperate and please don't think I don't sympathise but you may find other sleep suggestions that really work for you. Good Luck. These few months will whizz by and before you know it you will have a little girl not a baby. please enjoy them.
