DS2 is 5 weeks old and waking two hourly for feeds during the night but grunts and strains all night long so hardly having any sleep myself. Since he arrived DS1 (3.5 years old) has massively regressed and is waking up every night. Last night was the worst yet, he woke for the day at 2am and didn’t go back to sleep. I am beyond exhausted. I am just looking for some reassurance that I will get through this and it’ll pass :( also any tips to help DS1 with the big change at home? He hasn’t shown any jealousy in the day but has started asking for a dummy and nappies on and with the night wakings seems to have regressed a lot.
