Just care for them. When they are babies they just need to be loved. Also obviously feed them, change diapers when they need it Lol 😂. They sleep a lot, my advice when they sleep, you should too. You will need it and because you're going to be up a lot when he or she wakes in the middle of the night to get fed or change it diaper.

Thanks you for the advice! I've read that sleeping is a thing the first months hahaha

Yes the first 3 or 4 months or even 6

You're very welcome 😁. Also you are a photographer so you will no doubt have pictures of their child life. What ever you do don't blink or you will miss them grow up
