My DD was still having overnight feeds at 15 / 16 months. It was hard as I was working full time, but I took her into the bed with me, let her feed, while I dozed, and if I feel asleep all good. After a time when I noticed that she had finished/ had fallen asleep I took her back to bed. She did that until 3 when I stopped her from BF.
Sometimes it was 3 x a night, somethimes only 1 and yes sometimes it was only a comfort thing.
I was told to wean her off, stretch out the feeds etc, but working FT was hard enough and to wean her off, let her wait 30 min etc needed me to be awake while I wated the time so it was actually easier when I let her come in.
Yes it was annoying at times, yes I could have done what others had asked, but if my child still felt that BF was needed then I did it. It was only at 3 yrs that I really had enough, she would have kept going, but I told her that it was over.
At the end of the day you either need to be done or not done. If you are not done keep feeding your baby - it is perfectly normal for your child to still BF overnight despite people saying it's not necessary etc. At the end of the day - it is normal and acceptable. You just need to be aware that there may be times you are tired etc. Maybe reduce what you can do - be realistic. If you want to keep BF then less housework happens. Yes maybe you're at home all day, and maybe you 'should' do housework, but anyone with broken sleep is not at their best, so prioritise. If BF is what you want to continue - pick something else that would be lowered (housework is always a good one to reduce as far as I am concerned)
However, if you are done, and you are TOTALLY happy with that decision then you have been told some steps to wean her off and you can do that and that needs to be fine for you, and not anyone else telling you it is fine/ not fine.
I know it is easy for me to sound as if it is easy - and I remmber many times when I thought exactly like you. At the end of the day - this too will pass, you will do what you believe is best for your kids and in 3 - 4 years time when you see your prefectly happy/ healthy kids you'll know you did the right thing. xx
