After my DC2 was born I allowed myself to be emotionally blackmailed into having my mother to stay (partly because my father was so insistent that she wanted to help and would be heartbroken if not allowed to, partly because of that mantra well meaning clueless people chant about accepting any and all help offered with a toddler and a newborn). She marched in, took the baby, sat in my breastfeeding chair, and remained parked there clutching him and telling me (immediately post C section) to get on with cleaning while I had her there "to hold the baby". She complained about our meal times (too early for her, suited the toddler and DH's work day but that was met with a condescending grimence and patronising comments about adults who are early) complained about the meals I cooked ( easy one pot meals the toddler liked and I could prepare as and when and stick in the oven were too heavy, she'd prefer "a few bits" I.e. an extensive buffet of shop bought coleslaw, potato salad, sausage rolls, cheese's, different breads, green salads, grapes, chopped crudités and dips, etc etc but wasn't willing to drive to the shops to buy all that stuff) and didn't so much as put her own cups in the dishwasher as she felt (despite being frequently assured to the contrary) we'd have our own way of packing it. She didn't so much as boil the kettle. She handed me her dirty underwear to "just throw in with yours" she spent hours in the one bathroom, and complained about the lack of mirrors in her room and thought DH might pop out and buy one and hang it for her - she also wanted me to drive her shopping as neither of the jackets she'd packed were quite right for the weather. The only "chore" she did was once in two weeks to have DC1 in her room first thing (I thought maybe if I asked her to do something I'd resent her less - DC1 was an early riser and my mother wasn't getting up until 9am, then spending an hour in the bathroom, then coming down to take the newborn off me and order her breakfast 
- predictably DD made a mess with toys as she played while mother dozed for a couple of hours, so later in the day after much bemoaning of the mess my mother shovelled the toys randomly back into all the wrong places (seriously pieces of jigsaw chucked in with the Lego and other pieces of the same jigsaw in with the cars, pens without their caps chucked in with the toy kitchen stuff type "tidying") then spent the rest of her visit telling all and sundry how we'd never have coped without her to tidy up after us 
After two weeks we had a fight when I told her that I didn't have a second baby because I specifically didn't' want one and wanted time to clean and wait on people, and that holding my newborn all day and refusing to give him back except when I insisted wasn't helping me at all. She cried and laid on guilt trips about wanting to bond ... She then went home and told everyone how helpful she'd been and how I'd said I didn't know how I'd cope when she left. Seriously she was more work and less help than a couple of extra toddlers!
After hearing all about that a friend (who had stayed with us previously alone with her toddlers for almost a month without problems) came to stay after the birth of DC3, and told me on arrival that I could "get on in peace" as her 3 and 5 year olds were there to hold the baby... I assumed she was joking as she hadn't let either of hers out of her arms / sling as babies, but oh no - within a day she was complaining that the kids had been looking forward to looking after DC3 and she'd told them I'd be "relaxed" about handing him over so I could "get on" because he was my third, and mothers of 3 are always grateful to have someone to take the baby (a frigging preschool child apparently! I had preschool children of my own, had a wanted a 3 or 5 year old baby sitter to hold my newborn without close supervision - which strangely I did not!)
People are very strange when newborns are around - not just mothers!
My favourite guests left presents on the doorstep the day they knew we were coming home - I emulate that tbh.
In laws visited in hospital briefly (15 minutes) then invited us to theirs when we were ready - also works. They didn't meet DD til she was 5 months old due to living in different countries when she was born but have a closer bond with her now she's a preteen than any of my family who met her as a newborn.
