My DS is nearly 5 months and is now fully bottle fed. Up until now I have been feeding on demand. However, he has stopped 'asking' for milk during the day and gives no indication of when he's hungry - he's just busy playing or napping. At night he will wake for a feed but during the day I am guessing when to give him a bottle.
At this age what amounts / timings do people do for bottles? His naps are generally 9.30-10am, 12-1.30pm, and 3.30-4pm with bath and into bed by 6.30pm.
