What are some of the challenges with a new baby?

From my personal perspective the greatest challenge will be accountability to the elders. Why didn't you do this? Why is baby not drinking? Why is baby crying? All the questions that you have to answer and your actions explained. Followed by the breastfeeding challenges posed. Latching, supply, falling sick, milk strike, sore nipples and whatnots. Then comes challenges to the relationship you have with hubby. Differing opinions and sensitivity to issues will lead to quarrels.
