Addie is 14 months old and we do 3 a day, I am currently trying to cut out the lunch time feed. I do first thing in the morning and to go to sleep at night. I will keep going with these two till either she gives them up or I will see how I feel about it when she turns 2!! She started sleeping through the night at 11 months so was lucky to give up the night feed then. It has made a huge difference to my energy levels too(not being woken!) My DH got up to her the first couple of times when she woke during the night so she has forgotten about the bb in the night time.
I think just go with your gut and what you and bub want. My girl would be feeding 4 times a day still if I let her, but I need to cut back for my energy and feel like I have a bit of me back. I do love the feeding though I just need to stick with twice a day.
