I’m a mom of 6 and can assure you that hormones are definitely real. My advice is to be really easy on yourself and everyone else.
Go to the very basics: Food, sleep..and love. Lay on the floor half asleep in a safe area and let the little ones be around you or crawl on you so you know they’re safe. Do not clean. Do not plan. Repeat, do not plan. Do not worry, do not make major decisions unless you really really must. Do not do anything except keep everyone alive and realize a miracle is occurring within your body. Really, most things will be handled over time. This time of vulnerability and inability to “do” a lot is a different season. (You are doing something miraculous with God by the way.) We realize our agendas are not so central to the world. God working within us is, however.
I don’t know your specific situation, but if your husband is very busy working or otherwise unable to assist you, you can still do this. Do the minimum. It’s ok to have cereal for family dinner. People have eaten much worse, or less, and lived. Only do the minimum of laundry necessary…so wet things don’t mildew.
This time will pass and your sense of self will return,..in a new way., It’s so hard to remember in the middle of it all. Rely on God. Pray. Really believe He can help you; the Holy Spirit can carry you. Look in your little ones’ eyes and kiss them. It’s ok if you shut your eyes and doze.
