Re: is this the end?
Babies often take a bottle instead of nursing because bottles are easy. A bottle will generate milk flow even with the sloppiest latch and laziest suckling. And unless you are cradling the baby while feeding him by bottle, the bottle is something baby can take with him as he wanders around the house, playing. In his mind, that's a huge time-saver. He can eat AND play!
If you nurse just in the morning and at night, you will maintain a small milk supply. I nurse my 3 year old just once or twice a day and still have milk- but it's a really small amount. I rarely hear her swallow, though she usually has milk in her mouth after I nurse. She gets maybe a few teaspoons of milk. If you can pump during the day or at night, you'll maintain a better overall supply.
