Aww puppies sorry your mum isn't as supportive as you'd like
Mine was really involved - she was pregnant as well so we were great sounding boards for each other. I lived more thna an hour away while I was pregnant and I was working full time, and she was running a business and had my 16 & 11 year old brothers so we didn't see each other a lot, but we certainly talked heaps.
What's your MIL like? My MIL was a great resource for support as well, maybe invest some time in devolping a better relationship with her? Good luck sweetie.
