Breastfeeding working moms

Hi moms! Just want to seek some advice, my baby is currently turning 3 months and everyone around me is bugging me to stop breastfeeding and just pumping. Reason being im going back to work soon and it’ll ease everyone’s job- infant care and family members. My baby currently won’t sleep till she latches, not sure out of comfort or milk. I work as a teacher and for 6 hours straight, I teach. I have no breaks in between so I’m worried I can’t pump at work. My baby will be in infant care for half day, thankfully, since I work for a short time. I don’t want to stop breastfeeding her because of the bond I have with her but if I have to, how do I do it? She has yet been able to sleep on her own without me, and she seeks my nipples for comfort too :( #advicepls #firstbaby #worryingmom #pleasehelp
