Husband’s pushing to quit breastfeeding journey

Hi all, as the title says, my husband is pressing me to quit the breastfeeding journey. My daughter is 18 months and she’s down to two feeds a day. His reason is that since a month my letdown has, well, let us down. It’s no longer there or hardly. It takes really long now, pumping or breastfeeding, to get the same amount as before (i can tell because i count her sips, it’s very slow, down to like two or three a minute). Understandably, my girl gives up halfway but still points to my breasts that she wants more. So the rest is given to her with a bottle while i pump. My husband presses to quit because he thinks at this age the bottle is bad for her teeth and speech development (not the breast). I already asked what if we give the milk in a sippy cup but he still just wants to be done.

But i don’t feel the same way. For starters, i think the letdown problem is temporary. At the moment i am really run down with stress and fatigue. I already suffer from PTSD and probably run high on cortisol anyway, which is the opposite of oxytocin (which makes the letdowns happen). So i’ve had letdown problems before throughout the past year and a half (not like this though), but i’ve always worked my way through it. And the other reason is that my daughter doesn’t seem to be done either. She regularly asks for the breast for just a few comfort sips and i happily give it to her. I don’t want to give that up.

Has anyone else ever struggled with this? (The husband pressing you to quit or the letdown issue). Any advice is greatly appreciated. Oh and the oxytocin nose spray was a lifesaver before but unfortunately they discontinued making them in my and surrounding countries.
