I have only been pumping to provide the LO with breast milk for almost 2 months . Now I pump every 3 to 4 hours and I only get about. 4oz which is what my LO eats . I'm concerned because I know he will start eating more and I'm not producing that ..I have tried to latch the LO but he gets on and goes to sleep , but I don't think it's a good latch ...Any suggestions ??
