I've been expressing before bed as since hubby is giving DD a 9:30-10 dreamfeed with EBM without expressing would mean my boobs are not drained between 6:30pm and anywhere between 3:30 and 5:30am - she wakes up randomly at night at the moment. She's definitely switched into a 3-4 hourly daytime feed pattern at the moment though she does still ask for a 2 hourly maybe once a day or every couple of days.
