There is no such thing as a stupid question
Since your LO is older you'll find the Solves all your problems more to what you need. secrets is more for younger babies.
I agree a set wake and sleep time is a great starting point.
As is making sure your LO is not snacking which is what it sounds like your LO is doing. I understand the want to do eveything for your LO and to make sure she's never hungery, however avoid the trend to feed at the first sign of grumpyness, its not always hunger. For example with her age if she eats at 7am then is cranky by say 8:30-9am its more likly she's tired, or overstimulated then hunger. At this age its ok to feed more to a routine then to demand. Whats happening I think it that thats how your LO now assosiates comfort and sleep. When she is upset or tired she is bf.
I would suggest (and you'll read this with EASY) that you avoid feeding her to sleep, and the feeding as soon as she is upset. Instead give her the lion you mentioned, or even a cuddle, and you can even leave her be for a few minutes to see if she can settle herself. (as long as she isn't crying, please don't leave her cry)
The idea behind EASY is the routine of it Eat Activity Sleep You time, more then following the clock. Following your LO's cues is the idea. It takes a little practice and some getting used to.
You are an excellent mom and I know you want whats best for your LO. You'll be in for a few rough weeks, but I know you can fix things up for you and your LO.
For eating if your LO doesn't care for puree's don't be afread to introduce soft fruits, veggies, and other foods. Do so slowly just like you would puree's. Some LO's don't like the texture of purees, my DD lived for a few months on banana, bread, green beans, sweet potato's, cheerio's, some other cereals, and cheese. (9 months for the cheese or ask doctor) Take it slow and watch her but let her try them out. Try and give 2-3 meals (small meals bout 3-4oz each, more or less is thats what she wants) Follow her lead.
As for starting EASY take a few days and just watch your LO. Really watch her, try holding of bf a bit too if you feel comfortable, not enough to ruin your supply, what you want is steady feed times, not a drop in bm. It'll be a balenceing act for you. Ask the wonderful ladies in the breastfeeding forums they can help you with that.
For 3-4 days write down everything you do all day with her. Find her paturns. Feel free to post them her we can help you with them. Then you can start by weaning the feed to sleep assosiation, just do activity (even a diaper change if need be) so she learns its ok to sleep without it. Also read up on Pick Up/Put down your going to need that, have your husband read up on it too, it'll actually be better if he does it since he wont smell like breastmilk, and it'll be less tempting for him to feed her
I know some mom's leave at night for a few days (if you feel comfortable, Tracy did this with a family on her show as well, though I think the baby was a little older I'm not sure) The key is to find what works for you and your family.
I wont lie, it'll be a lot of work for you both, you have to reteach her new self soothing habbits, but you also have to retrain (so to speak) yourself too. Just be consitent and it will get better.
