I'm thrilled to read that comments were helpful and that they've prompted you to take some action (e.g. coaching) and helped you to rethink some things. If you've had experience working from home and have that entrepreneurial focus and drive, that's great. And you do understand that working form home is WORK - which many of our posters don't fully understand.
Of course you want to give your daughter the things you missed - such as parents at school events.
Let me suggest a couple of things: being there for your daughter is work, and it has value. Always measuring your value and contribution in terms of money is unfair to all of the women and the low-paid care workers and teachers who aren't making what they deserve. So don't put yourself down, and don't, by association, inadvertently put others down.
Second, try to contain the "going nuts" buying things for your daughter. Yes, it's fun, but is that what she needs? Let me suggest that you redirect some of those dollars, and give her stuff that will help her grow and have wonderful memories. So, instead of another outfit or cute pair of shoes she'll outgrown in 5 months, how about buying a membership to a children's or science museum? I had fun shopping in resale shops for my son (lots of perfectly good clothes, and it was no different than getting cute hand-me-downs from friends), and having money left over to give him experiences. We used so many free resources, such as our public library's passes to dozens of area museums and attractions. We'd try them out, and if we found one that we felt would be a favorite, we bought a year's membership. It made it possible to go for free, and just stay for a child's attention span of an hour or two, rather than turn it into a long day because, "Hey, we paid full price for admission." Exhibits change, and our child's interests and abilities changed over the years, yet we always found we could do fun things. My son is grown now, and remembers those times we spent together. He doesn't remember one pair of shoes or one pair of pants. Instead of me buying him a toy in the store, he'd stop in the museum gift shop at the end of a day of good behavior, and we'd get a member discount on something that piqued his interest at home and his pursuit of knowledge. It created a work ethic in him as well. So think creatively about the memories you want to create with your child, and use your dollars in a wise and meaningful way rather than the fleeting fun of an impromptu purchase.
You could also save up for "experience" type vacations that will give your child great memories. For example, we rented an RV a couple of times and traveled around to see the sights. We experienced campgrounds without having to rough it in tents (some people love that but we don't!), our son met and played with kids he didn't know (which developed his confidence and social skills), and we saw some great landmarks (museums, caverns, etc.) while having wonderful bonding time on the drive. While this particular experience might not be for you, I hope you'll use the idea and try some other things that are a mix of luxuries and simple times and pleasures.
