Goodness, I left my baby with my mum and husband for three days when she was 8 months, then again for a week when she was a year. Once for a break, once for a week's training I needed to do to get my Degree. Pumped lots of milk for them to use and left them to it. Dad was very hands on and my mum is closest to a second mum for my daughter, so while I am sure she noticed I was gone, she definitely felt safe and loved with parental figures too.
I left her for a week in similar way every six months ever since. I similarly held the fort for whole weeks or more when her dad was away for work. From age six she would spend a week with grandparents, without either parent, several times a year, and from age 8 that extended to two weeks at a time.
Even with that, until 6, she was with me 96% of the year! And after that about 90%
If someone truly doesn't want to leave their kids, fine don't. But the comments of 'why would you ever want to be away/ what's the point of having kids then' or 'how can you dump them like that' are just ridiculous. And sexist. I doubt very much we would doubt a man's fathering or the point of him having kids for going away for two days!
DD was very enriched by her time away from us - she is very securely attached but with an independent, self reliant spirit. She developed a proper deep relationship with grandparents, got to spend wonderful holidays in other countries that we couldn't have taken her to or stayed as long in..... and the grandparents loved it. And I was able to be a way better mum for having some chinks of time in my life which were for me - whether personal, having adult friendships, continuing to develop my career, have time as a couple, or just simply rest.
I respect mum's different choices to be always with their kids, but I hope you find other ways to nurture the parts of yourself that are not about being a mother.
