Nipple, capacity, material... Which bottle to choose?

I don’t know if this may seem silly, but has any new moms experienced feelings of fearing that your newborn won’t know that you’re their mama? I’ve been feeling this way because I’ve been spending my maternity leave at my parents house (my son was born almost three weeks ago) and my mom, dad, and sister has been helping me. I’m worried that he may not know if I, my mom, or sister is his mother. Majority of the time, either my sister or my parents “take the night shift” as we say, so that I can get my rest. But now, my mom guilt is setting in and what if he doesn’t know that I’m his mom? I spend as much time with him during the day as I can, but of course my family wants to sometimes hold him and play with him during the day as well. I also tried breastfeeding him in the early days but my milk supply was slow at coming in and I was worried that he wasn’t getting enough, and I like knowing how much my baby is getting. So once my milk came in a little more, I just pumped and fed it to him in a bottle.When I woke up this morning to try to nurse him for the first time in a while, he wouldn’t really latch. I’m so scared that he may not know that I’m his mom anymore ? I’ve addressed my concerns to my family and they all say that he definitely knows that I’m his mama and that they have no clue why I feel this way. I just love my baby so much and don’t want him to feel like im abandoning him at night. He’s very colicky and my mama said that she takes him at night because she can tell that it scares me when he’s in pain. I also want to mention that my breast were very sore and would hurt when I did attempt breastfeeding. Also, they were cracking and peeling, and there was one instance where a big piece was in my baby’s mouth, which freaked me out. So that’s when I decided that I would just feed it to him in a bottle along with formula supplementation.

I feel like I'm alone sometimes ... He works, hard .. when he comes home in the evenings he takes the baby but at most it's like 2-3 hours before we .. I .. put the baby to bed. Even then he will set the baby down while we're eating and just completely ignore him crying .... I am home with the baby all day. I do majority housework, unless I ask him to do this rare thing. I cook majority of meals. I'm up with the baby at night .... Don't get me wrong, he is a good man ... Just ... seems a little out of touch and maybe that's my fault cause I just let it slide that I didn't ask him to get up at night cause he would just lay the baby down after feeding him the bottle and then crawl back into bed without making sure the baby was actually asleep .. which meant about 5mins after he got back in bed the baby was screaming his head off. What do I do?
