I'd highly suggest looking at hundreds of baby photographer's websites and youtube.
You will need to find your style and the type of look you want. There is alot of baby photog's using brightly lit window light shooting in a studio or a living room etc. Then there's shooters that use primarily strobes shooting small apertures (f/8 to f/11) with heavy emphasis on props and cute outfits.
What you will find its baby photogs put alot of money in props, props, props and most importantly props. There will be alot baby girl photos with the us of subtle headbands to "in your face massive/loud" head bands. This is where some people dig this look or hate it.
Skills must be developed in handling the babies. This is probably 1 of the tough obstacles. Every single baby will sleep differently. Some may be forever light sleepers and some heavy sleepers after a bottle.
Be prepared to spend alot of money on props. This is where photog's must constantly change the backdrops, props, outfits to stay fresh when displaying a porfolio.
As you know we can only pose a human body in so many ways. This is where critical eyes requires alot of props to identify "something different" from session to session. Adults are different because big people, smaller people cannot always be posed identical from couple to couple. Babies on the otherhand can virtually be posed in an identical manner. This is where once hammer down the skills in posing the props and backdrop is your variables in changing the scene.
You are entering a niche field. Try to go to mini courses.
If you like the strobe look then that is something to consider. I fall more along the lines of softer shadows and use constant lighting or window light. Since newborn photography is basically woman dominated I've kinda dropped that type of shoot. I'll do family photos but kicked back on babies due to $$$$ investments in keeping up with the joneses in heavy prop usage.
there are other version with more lightbulbs. The more expensive version is made by Wescott spiderlite. The one I've listed will give you a taste of that type of light made overseas in China. They work well but not high quality like the wescott. Using constant lighting will be a tad harder on the camera because you maybe required to shoot in the higher iso region.
Using this type of light you can have "whatyouseeiswhatyouget" or "wysiwyg". Softer light but as long as the baby stays in one position you just snap away not to worry much about exposure because it will be consistent.
Please do more research before pulling the trigger on gear.
