The internet definitely makes it easier to be prepared with baby essentials because you can find almost anything you need online these days -- except perhaps for a good night's sleep, which many new mums will gladly pay a premium for!
Since we're on the topic of online shopping, I'd say another essential item to have is a baby carrier or sling. It's incredibly handy for outings and frees up your hands for other tasks (or for holding your coffee). There are so many types out there -- soft wraps, ring slings, structured carriers -- each with their pros and cons. It might be worthwhile researching your options online, finding one that suits your lifestyle and wearing preferences best.
With online reviews and guides, you can avoid making expensive mistakes and select a comfortable, durable carrier that grows with your little one. This is definitely something I'll be adding to my list!
