Can a baby be addicted to caffeine?

If so what are the signs? My daughter is 6months old and for the first two months of pregnancy I didn’t know I was pregnant because I was just coming off the pill and didn’t think I’d get pregnant right away and my periods were always unreliable to say the least. So for for those first two months odd drink anywhere from 3 shots of espresso a couple of times a week. I don’t know what the symptoms will be but I’m really scared she might be addicted and I don’t know how to help her because I’m a first time mom. What are some symptoms? Thanks. Please no judging. Obviously as soon as I found out I cut the espresso out so don’t shame me because that is totally not cool and we’re not here for that.
