Ok maybe you can slowly cut down the 2 bottles that you pass to the infant care 1st... one at a time and ask the centre to feed FM. The evening feed can be substituted with a dinner meal. You have to drop the feed one at a time..But why dont't you continue feeding the morning and last feed till your child is ready to wean himself at least some bonding time for you and your child?
This was how i did it for my dear daughter. But around 7 mths she started bitiing me and i stopped totally.. I was very sad when she continued to do that..and also about stopping then..but at one stage when you feel that you need to stop.. dont't feel bad about it!!
