breastfeeding

Lauran
I'm planning on breastfeeding and pumping when baby is born. I have a wedding when baby will be 4 months old. My mum has offered to keep baby and I'll take my 2 yo with me. But if I'm still BF'ing/pumping will my supply go down if I dont nurse as much through the day? I'll take pump with me and pump a couple times. Hope this makes sense haha
