I remember those nights of walking the floors because my daughter had colic for the first 3 months so sleep was a luxury when it came, but then I had a toddler that was 2 so again so sleep. No wonder my hubby says I'm nocturnal I can get by on next to no sleep.
When the baby is asleep with the face of an angel you will forget all about the crying and walking, I don't have any puppies but I can loan you a boxer that think's he's a lap dog and crying babies don't bother him at all. Wish I lived closer I'd offer to walk the floor so you can sleep
