First night sleeping through the night

Katie • Mom of a lively amazing little boy (9.30.15) and sweet silly toddler girl (8.16.17) busy and loving it!
I hoped and prayed for this day to come. After 5.5 months of being up every 1-2 hours at night I finally gave in and tried sleep training. Last night he slept for 7.5 hours! I don't remember the last time I was this rested! Only issue is I usually nurse him 3-4 times at night so I'm sitting here pumping at work and I don't think I have enough storage containers. It's like Holy Milk!!
