Re: About to Start solids with lots of questions!!
At 9 months it's probably not necessary to give purees. Barring medical issues she should be developmentally able to eat table foods (that generally happens around 6 mos old). Offering your child appropriate table foods gives them the opportunity to regulate their own intake of food, so you don't have to worry if you are feeding them too much or too little because they will take in exactly as much as they need.
If you choose to give water, I would give it in a sippy cup or normal cup. There's no need to introduce a bottle at this point. It's probably not necessary for hydration, since she nurses frequently, but it won't hurt anything either.
Here's an article you might find helpful, keep in mind this article uses the European meaning of the term "weaning" to mean beginning to eat solid foods and not the American meaning, which refers to stopping breastfeeding.
“We are not put on earth for ourselves, but are placed here for each other. If you are there always for others, then in time of need, someone will be there for you.”
