I had a whole blurb to give you, but didn't realise I had been logged out when I posted it, so lost it all.  There's a trick for young players

Anyway, same with me - ditto what Emma said.  Those times really worked for us.  The only difference with me was I would wake Gabrielle initially at 11pm and feeding her then and that would take her through to 7am.  We did that for a month or so, then we gradually bought it back 10 minutes each week until she was feeding at 10pm and she would go through until 7am.  Then when she started solids, we stopped waking her and she went from 7pm to 7am the first night!

I didn't start until Gabrielle was about 8 weeks old, but that was because I could not work out a routine that worked.  I tried right from when she was 3 or 4 weeks old, but Gabrielle wouldn't have a bar of it, but when I did the times that Emma listed, she slotted straight in. How I started the routine was on the first day, I woke her at 7am and fed her then - even if she had only fed at 4am.  Then 3 hourly after that through the day.  If she wasn't awake at a feed time, I would wake her up.  If she woke up earlier than her feed, we would have a bit of playtime and still feed her at the allotted time.  Some days were a bit skewif, but 99% of the time were good.

I needed a good routine because I was coming back to work when Gabrielle was 6 months old, so didn't need to be getting up in the night as well.  Good luck though, different things work for different people and I found this really worked for me.  It may not happen the first day, but at least will give you something to work towards.  Hopefully some of my incessant babble will help you
