Great software for legacy planning
Format: Paperback
Great info. Use an AI to figure out what you need and to educate yourself, but this helps a lot for legacy planning for most of us.

Pretty good wipes
These wipes are great and I love that each pack has it's own lid. These are medium thickness (not as thick as Huggies, but not as thin as some store brands) and do a good job cleaning my baby's behind. We typically need 1-2 wipes for #2's depending on how far up her back it travels lol. I got these at a great price and am very happy with them.

Sturdy and Effective
The inside of a diaper bag is not a gentle place, so anything I put in there needs to be sturdy enough to handle the bumping, shoving, and crushing. The pouches are not rigid, so they can fold, but are thick enough not to tear. The lid opens and closes smoothly and I have not had any of them wear out or stop staying closed before the wipes run out.
The wipes have a pleasant scent and feel clean. The wipes are the right thickness for most jobs, but are not what I would call 'thick' wipes nor are they 'thin'. The oils and chemicals used are gentle enough for older babies while still getting them clean, but I would recommend something more gentle for newborns.
The four pack was a great value (12 pouches total) and I would recommend it to any fellow parents of infants or toddlers.

Loyal to pampers
Size: 504 Count (Pack of 1)
We are big fans of pampers! I love being able to buy them on Amazon at a lower price. I love the ease of the individual packaging as well as the fact that there is not disgusting smell to these wipes. Even the 'non scented' wipes tend to have an odd smell with other brands. These are very soft and do not feel as if they would irritate babies bottoms.
