Mother in law problems


Okay so it’s got down to the last straw now I can’t handle it no more! She just keeps taking over she brought like 10 packs of nappies she brought a cot mobile even though iv told her I have one already she brought a changing mat even though I told her I want to buy it she brought clothes and got her work mates to bring in there grandchild’s clothes so now I have like 3 bags full of clothes so there no point me going clothes shopping now :( she wants to feel my belly all time I just feel like she taking over sometimes feel like popping little man out and giving him to her if she wants to take over she can have him. Just asking really how to politely tell her to back off. Thanks
