What are some of the challenges with a new baby?

Tons! Your life literally takes a whole new turn and the house WILL get messy (unless of coz you have help). First there's the extreme loss of sleep. Newborns generally wake up 1 to 2 hours for milk bcoz of their small tummies so that means you have to tend to them. Once their asleep, you have to pump as it is encourage for breastfeeding mums to pump every 2 to 3 hours so increase supply and to avoid engorgement. The very little time you have in between is for laundry (you'll be amaze at the number of changes a baby has in 1 day), house chores, toilet breaks, meals and if you are lucky, 30mins nap. If you have an understanding husband who helps out, good for you. Tag team so that you'll have sufficient rest when he leaves for work. If you don't, you'll find yourself stressed up from the lack of sleep, irritable at the slightest cry of your child, mad at yourself bcoz you can't figure out his cries/can't produce enough supply which leads to mummy guilt. And the most noticable thing, your relationship with your spouse. Your baby will naturally become #1 priority and this will definitely have some sort of effect on your relationship.
