Good for you! Yay for being motivated and taking charge to improve your diet!! I'm not going to lie, it will be hard because cooking from scratch takes time. What helps is preparation: grocery lists, meal planning, even ingredient preparation ahead of time so that the actual cooking process is easier. However, do make sure that you do allow yourself and your family some allowances, especially when time gets tight. It's okay if your family has some pre-prepared foods and your baby gets steamed carrot sticks instead of what you are eating; in fact it's even okay if he gets purees. BLW is a fluid process and everything is situation- and baby-dependent. The most important thing is that he gets fed and gets the appropriate nutrition that he needs.
For resources, I am a fan of this book!, but check Amazon, they have a lot of good resources. For websites, I am a huge fan of Wholesome Baby Food, and skinnytaste. Skinnytaste is geared more towards adults and families with older children (who can chew), but you can go through her recipes and parse out the ones that would be appropriate for BLW at different ages. Additionally, skinnytaste does substitute a lot in order to lower calories, for example, low fat cottage cheese instead of full fat cottage cheese. If you use the recipes for your baby, you'll want to add the fat back in.
Good luck!
