Giving bf baby bottle of expressed milk. Advice, positive stories please!

[Mammmoo]

Dc1 was a staunch bottle refuser and caused many issues/cost us a fortune in bottles. In the end i gave up and directly bf until a year.
Dc2 is 6 weeks, was bottle/cup fed expressed milk until 2 weeks due to jaundice and losing weight. Now bf is established and going really well. I would really like to now start giving the odd bottle of expressed milk to allow me a few extra hours of sleep, to go to the gym or to go and get my roots done - selfish reasons I know but for my sanity as much as anything. I love bf and want to carry on for a year.
We were going to attempt a bottle this weekend but now I'm losing hope my nerve. What if she doesn't want to bf afterwards? Is it too early? We waited until 4 months with dc1 and I think that was too late.
So basically I want opinions, stories, advice...anything. As it stands currently I think my fear of being rejected along with very recent memories of how difficult establishing bf was are leaning me towards not doing it.

My DD had 24 hours of bottle feeding in NICU after she was born and when I took her back postnatal she was still willing to latch. I thought I'd missed my opportunity to breastfeed her.

She will attempt to latch on to virtually anything to be honest.

6 weeks is fine. The odd bottle shouldn't effect things

My ds had regular bottles of ebm from birth due to tt. Didn’t adversely effect bfing but the wee bugger decided to refuse all bottles at around 3mo anyway 🙄
I ended up having to train him into cup feeding at 6mo.

Basically I reckon they’ll do what they do and we have very little control. Do whatever suits you now and then roll with it.

I started giving DD a bottle a day at 6 weeks and it felt like the perfect time; breastfeeding was well established so it didn’t effect that and she took the bottle no problem. When she was about 4 months I was doing half and half and she was also fine with that. I was told though that when you give a bottle you need to do it relatively regularly as if you wait a month or few weeks between them then they may start to refuse
