Exactly.
With DS I was totally unprepared for the relentlessness of breastfeeding despite a very generous supply. I was brainwashed into breast is best by MW's and HV who talked it up but couldn't help with problems - at all! Some of the problems were due to my inexperience and also it hurt - a lot.
After too much mastitis I gave up when DS was 8 weeks and he transferred to formula - he and I became much happier except the guilt tipped me into depression because I thought I had failed. Some women need permission to stop.
In the first world with good, clean water, formula is fabulous if it suits you best. Frankly I found making up bottles a doddle compared to the endless hours of breastfeeding. DH could give a bottle and I could do my hair, cook the dinner, etc. BF is not compulsory and in the first world the benefits are miniscule. Your baby won't remember this time and benefits most from a happy, rested mummy.
FWIW DS developed bronchiolitis, asthma, eczema, ear infections. However DD (who I breastfed until 8 months rather than 8 weeks), also developed bronchiolitis, asthma, eczema and ear infections).
DS's uni was marginally lower ranking in his subject than DD's!! he went to Oxford, she went to Cambridge
They remember their favourite dinners, their first goal/concert, learning to ride a bike, snivelling into your neck like babies the first time their hearts are broken. Those are the things that cement relationships. Love makes you a good mother, not breast milk.
I do not doubt breast is best, but I question if it is best if mother and baby are sub optimally happy and content. This should be a happy time. All mothers struggling to breastfeed and wanting to stop should be empowered to stop and given permission to do so if that is what they want.
Feeding my dd was easier than feeding ds. Probably a combination of more realistic expectations, her feeding more easily, me having learnt how to do it and to ignore the often utter nonsense that leaves the lips of midwives and health visitors.
Good luck op. You do what you want and/or need to do in your heart.
