HI there, I thought I would try and help you out, what I founs helpful was to guide my lo I wake her and let her play, if she is tired, I will put her to bed, ad now she has preety much slipped into a 4/4 routine, it did take a while, about a month for me, I relaxed on trying it for a bit and then I looked at dh and realized she had begun to do it all on her wn. The main advise I ahve been given is as lon as you lo is able to settle themselves,and the feeds are a good time apart, all is well.
Check out the march/april posts, as some of us are still trying to extend our routines, some of the advise may help.
Good Luck!!!
