Breastfeeding

JoJo • After 2 miscarriages Im finally a mother to our miracle baby. IVF/FET success.
I have read different articles online about how long a breastfed baby sleeps vs formula fed. Just wanted personal experiences on how long your baby sleeps and how many weeks are they with exclusively being fed just breast milk. It doesn't bother me getting up every 3 hours but it worries me that once I go back to work it would continue.
