I swear baby #2 is harder for me personally because I have been on the go since the day I left the hospital with my older son, moving, switching his school etc. running on the 2-3 [nonconsecutive] hours of sleep each night in between feedings. My son is 3 weeks and I am TIRED 😴 I return to work on Monday, a day shy of him being 4 weeks and I'm really nervous about fatigue effecting my performance and all around self. It already is making me forgetful (I forgot to pay 2 bills I swore I paid and forgot half of my groceries... twice!) i know it'll get better but with my job I handle Doctor/Provider accounts and claims and I am monitored for quality and volume and my supervisor is a perfectionist in work and as a mom and BOY do I feel like a mess compared to her as I'm practically needing to tape my eyes open 😭 am I alone???
