Never really read a whole book on weaning so probably won't be much help but I did borrow Finger Foods by Lennie Maizels from the library and found it very useful. The blw website is very good too and you can always just ask us
River cottage baby & toddler cookbook. Not a guide as such but has useful info and straightforward recipes for family meals with notes on each for young babies. Suitable for blw or traditional weaning.
