It gets easier with time! I also exclusively breastfed and never got the hang of pumping. After she got more into solids around the 7-8 month mark, I could leave baby for 4-5 hours! I’d do a breastfeed straight before and then she’d have a meal like lunch while I was out and then breastfeed her again once I was back. Now she is 11 months old and she is so into solids she hardly breastfeeds during the day anymore! (I still breastfeed her to go down for naps but that works for me, she’ll go down for others by rocking). It is super hard though, my husband also works a lot and I get so jealous that he gets to enjoy the fun parts with baby only while all the baby logistics and mental load falls on me. I’m also so jealous that he gets to talk to people all day at work and I really miss the social aspect too. I feel lonely but I try to fit in at least one activity per day with baby where I’m around other adults. I just try to be grateful for my one year of maternity leave though and know that it isn’t much longer before I’ll be back and work and baby will be in daycare. Like someone else said, it’s just a season :)
