HELP!! How do I get more milk 😭.

Mercedes • Mommy to a 18 year old daughter , 15 year old son, 5 year old daughter , 3 year old daughter and currently pregnant and due June 2024

My baby will be one month tomorrow, I was pumping about 3 ounces and now if I pump I get 1 . I even bought Lactation cookies and it doesn’t seem to help . She’s on my boob every 2/3 hours , so she seems to get enough , but I have no time to pump in between ? Do I pump any ways ? I’m trying to have some in freezer Incase I need to leave her with hubby if need be .. and right now I can’t cause I have no supply!

PLEASE ANY ADVICE!?
