Dealing with a narcissistic mother during pregnancy

I am 36 weeks pregnant and my mum is looking after my 2 year old, as I've been told to take it easy.

Taking care of a toddler is no easy feat, and I appreciate her for doing it, but she has been making little snippet remarks for the last 2 weeks.

She is sick of hearing that I'm pregnant and can't pick up heavy items, it's all my fault because she can't go on holiday, it's all my fault because my daughter is not using the potty anymore (even though she is in her care).

I lost my temper yesterday, because she was trying to get a rise out of me.

I'm seriously considering hiring a short term nanny until my daughter goes back to kindergarten in September, but I know there will be a family feud if I do.

Do I suck it up? Or hire a nanny?

Update: Spoke to my husband, and I'm going for the nanny option 😊
