As all paranoid parents are wont to do, my partner and I have set up a video baby monitor… to watch the puppy.
At 3 months old, we mostly use it to answer the questions “is she still asleep? can we still rest? dear God please let her still be asleep”. Which, to be fair, may not be too different for human children.
To her credit, Maddie has made pretty good progress at the whole sleeping thing. She typically only wakes us up once overnight, around 1 or 2 am depending, and is napping at a schedule of approx 2 hours awake to 1 hour asleep during the day. Which seems to be appropriate for her developmental level but is still nice to see.
