In Canada the recommendation is for LOs to start on solid foods around 6 months.
In the UK too. Also the WHO recommends waiting until 6 months.
I echo what Lindsay has said. Milk (breast or formula) is higher in calories and nutrients than what your LO can get from solids at this point. There really is no hurry to transition to solids and if there is too much solid food your LO might not get what she needs and become more hungry. Their tummies are so small at this age so you need her to be hungry enough to take a good milk feed.
If you are concerned about thirst I would recommend giving an extra bottle of milk alongside or immediately after the solids feed rather than water at this point, just so she doesn't fill on solids and water.
I never offered food before a bottle. Many LOs will drop one of the day bottles around 9 or 10 months or so and this would be replaced with a solid snack and a drink of water. the other milk feeds would continue as usual with solids coming roughly an hour later.
hope this helps.
