Hi Munaz,

We started from day one, but not the actual Week 1 routine. CLB says to start with feed every three hours with a four hour from 10 pm. If the baby has a formula feed at the 10pm with your husband there's a very good chance of him/her sleeping the four hours, as they don't digest formula as quickly as breast milk. Then after the baby is well in this and has regained birth weight you can try to stretch them towards the Week 1 routine (page 114). I think we started with 100ml at first for the 10pm feed, she didn't always finish if she fell asleep. There is a chart on page 63 which gives you a guide to how much each feed should have, I followed that at first. I think it's crucial to give them a bottle within the first two weeks, all of my friends and sisters who tried a bottle after 3 or 4 weeks could never get them on a bottle and breast fed through necessity until about 6-8 months even though they wanted to stop earlier and had to go back to work. One of my friends is lucky to have creche in at her work and still has to go down at lunch to feed her daughter.
I remember (she's 8.5 months now - seems a lifetime ago now!) that she started by only being able to have on side at each feed, probably for a few weeks, then eventually she was able to take both sides as she got stronger. You have to make sure you remember what side was last fed on. I kept a little note book and just wrote something like '7am. Left, 40 mins', sometimes you're so tired or drained from feeding you forget, so I found the diary helped to track sleep, vomit, crying etc.
I always tried to keep the 3am feed small (1 side, 20 mins if possible) so she could be weaned easier. After a month I started giving as much as possible in the 10/10:30pm feed then weaning the 3am with cuddles and dummy.
Anyway, she is 8.5 months and still follows the routines perfectly. She goes to daycare 2 days a week and follows it perfectly there too. My whole Mother's Group coincidently followed routines too (mostly Tizzie Hall, which is similar) and their babies, and one of my sister's baby all followed and have all been easy wonderful babies!
Good luck.
