Hi Tasha, I am still breast feeding at 15 months, I have managed to cut out quite a few feeds now and replaced them with cows milk, but it hasn't been easy. M has been a real boob-oholic
It took a long time to get her on to solids though, she wasn't on three meals a day until she was about 10 months. She wouldn't touch formula so I just gave her cows milk straight away. I let her drink her cows milk from a beaker and she loves the novelty of it so will drink more of it. I intend to cut out all the day feeds by 18 months and then will stop feeding her completely by the time she's 2.
I think it will all depend on your baby, she might stop herself before she's one or she might be like M and not want to give it up.
Hope this helps
