>>Breast feeding is going to suck for your wife/gf at first and she will want to quit and give formula These are a godsend according to my Mrs https://silveretteusa.com/ US website but should be able to find a local supplier. Well worth the price. Don't get knockoff/ or make sure actual silver content is on par. >> Buy lots of wet wipes Try also get reusable wipes when at home and just wash them keep costs low, same with nappies pro tip ;⁠-⁠) >> Co-sleeping will make your wife/gf's life easier. Stay away from sleep training or whatever it's advertised as. We tried to go this route and it failed every time. Free consultations and paid. Be patient and understanding. We co-sleep now because nothing worked for us. Everyone/baby is different.
