I know this doesn't really address the question as asked. However, due to a conversation in chat with the poster as well as other simultaneously asked questions, here is the best answer I can offer at this time.
There is a bit of a debate over when to wean baby entirely - in the US at least, but the standard is about one year to one and a half years here. There are a lot of things to consider when weaning - not the least of which includes the baby's nutritional health, mental well-being and immune health. Your other question here addresses some of the concerns doctors might have regarding bottle use in general.
A baby can be eating solid foods and still drinking mother's milk for years if mother and baby desire it to be so. What is best for everyone, as I said, is up for debate and quite individual. I thought this short article posted on La Leche League's website was interesting, though not very conclusive (and absolutely in keeping with La Leche League's purpose - to raise awareness about breast feeding and fully support a mother's right to do so as long as she feels is right). Here is what the World Health Organization has to say about it.
As a global public health recommendation, infants should be exclusively breastfed1 for the first six months of life to achieve optimal growth, development and health2.
Thereafter, to meet their evolving nutritional requirements, infants
should receive nutritionally adequate and safe complementary foods
while breastfeeding continues for up to two years of age or beyond.
Most doctors in the US will disagree with the two years part and shorten that number to closer to about a year so the American Academy of Pediatrics recommends that 18 months at most is the time for full weaning.
At our house, we introduced solids at about the times we would normally consider to be meal times (breakfast, lunch and dinner), but if Alice was hungry at any other time, her "snacks" were still mother's milk (or if we had been feeding formula, we probably would have used it). She also still got to nurse just before I left for work, when I arrived home, and right before bed. As she consolidated her eating habits, the frequency of nursing dropped because she no longer asked for it. At some point, she no longer needed to nurse right when I got home (and I no longer needed her to either) It wasn't painful - no one missed anything, no difficulty at all. Because I let her take the lead on how often she needed to "snack," she actually weaned herself - and earlier than I would have personally anticipated.
The spoon you choose to use is irrelevant to the bottle feeding if you are only using the spoon to introduce the new foods or, "solids." Using a baby spoon is ideal as it will be safest for baby, and easiest to use (grips for the parent, and all kinds of technologies involving the shape of the handle are available).
Continue using the bottle (or breast) for milk feedings, and just add the spoon for introducing other foods. Wean away from the bottle at night first by beginning to cut down on night-time feedings through sleep training and other similar methods. Slowly reduce her intake of milk and introduce a sippy cup as soon as you think she is ready to use one. The infant I care for already uses one for his water with his other foods at 7 months old - simply remove the rubber piece that causes a requirement for sucking and you can carefully pour in the milk/water/whatever if your child is unable to hold the cup or regulate outpouring of the liquid.
If there is a separate medical issue that requires letting go of the bottle entirely even at this early stage - I recommend a switch to a sippy cup rather than a switch to a spoon for this purpose.
