Not a dad but I have experience raising children from infantry. The biggest thing that helped me was to sleep in synchrony with your baby. Try to sleep when they go to sleep. Usually babies through their toddler years are to sleep for up to 16 hours a day. That was my biggest help

@daydre444mer yes, we try our best to sleep at the same time, but this doesn’t leave much time to cook, clean, do the laundry…. Anyway, we will get through this 💪
