Hi. My son is 4 weeks old. He is ebf. He can go 3/4 hours without a feed during the day then he cluster feeds early evening and will go 2/3 hours between feeds till midnight. After midnight he wakes every 1 to 1 1/2 hours all night. I am struggling to have any energy for my 2 year old in the day because I am so tired. Is this a phase? Do I need to wake him more in the day? Any advice would be appreciated as I am struggling. Thanks
