Positive vibes needed

I need some positive vibes here. We are 2 weeks with our newborn and we have a 19 month old. We are adjusting as a family, but every day is really hard. Our toddler is extra fussy and balancing a newborn fuss with that is overwhelming. Other parents who did two under 2 or similar age gaps, tell me it will be okay. Remind me the positives I have to look forward to.

My husband goes back to work this week and that will add a new mix to balancing the parenting workload. Both sets of grandparents are helping out, so we have a lot of support.
