Recommended - Baby Books
Torie says -"baby secrets - Jo Tantum and Barbara Want - was recommended when I wanted to get them to sleep through the night and it worked!"
Tess recommends 12 hours in 12 weeks
Rachael has this to say about the above books - "the above books go from very flexible, to very structured. The no-cry sleep solution is at the flexible end of the scale, and the Gina Ford is at the very structured. Babywise (in the middle) is quite routine based.
Emma also recommends The Baby Whisperer - "This was my bible for the first 6 months. It is not twin specific but it is all about understanding your baby and has sensible, gentle and flexible routines that work very well with one or more."
