To be annoyed that I have just had DD3 but my Mum acts as if I have know nothing

[Abubu]

I have just given birth to DD3 5 days ago. It is my 3rd DD but 2nd time of being a Mum to a newborn (as I had twins last time).

However my Mum still acts as if I know nothing - advising me on what I am doing wrong etc.

I expected it last time round (although it still got on my nerves) but this time I think she should accept that I haven't managed to seriously harm my other 2 children yet and maybe I am just about managing ok

Is this just a mother / daughter thing that I need to let wash over me?

I would tell her straight? otherwise it will continue to get on your nerves as she probably will continue saying it.
If you just say "thanks mum but I know what i'm doing" will she get the message or do you have to spell it out even more?
I had this with mil and did spell it out in the end

whilst her interfeering might be a tad out of control a simple conversation might help - maybe she doesn't realise she is being overbearing and your vulnerable post birth state might be affecting your normal mother/daughter resistance and making it hard for her not to step on toes

as someone who had to bury their mother 2 days before the birth of DD3 I'd be inclined to be grateful for the help/support/family closeness but try to resolve it without causing more harm than good

families are never easy

perhaps try saying 'oh you know mum I'm finding it quite easy actually half the work etc with just the 1 newborn. But perhaps you could take twins for a few hours so I can get some rest!!!'

That way you can actually relax for few seconds and it will get her out from under your feet.

Best of luck

dizzydixies sorry to hear about your experience but I'm sure you coped brilliantly and made your mum proud.
