Babysitter Needed

My son eats 3 and a half ounces up to 6 ounces every 2-3 hours but sometimes he takes 4-6 hour naps which is perfectly fine unless its evening times. He sometimes takes breaks when feeding so if he doesnt drink his whole bottle, burp him and let him fall asleep on his own but he eventually wakes up to eat the rest and sometimes may want more. He sleeps either on his back, slightly on his side, or he likes to fall asleep in someones arms or chest then be put down on his sleeping pillow.
