Breastfeeding Tips

Erlyssa
I pump and also use breast to feed my son. I wasn't sure when I put him on my breasts he was getting alot of milk because every time I take him he seems to want more but breast milk from the bottle do you guys have any tips to keep him latched on more and not want the bottle as much and I know I have milk because I can pump at least 3 or 4 60ml bottles for him. All advise appreciated thanks!
