feeding schedule for a breastfeeding-snacking baby

[Kie1]

Hello,

DD is 3 months and 3 weeks old and is sucking her thumb now which helps her to fall asleep quite easily (sometimes). I would like to start a routine for her. She is a bad sleeper during the day (catnapping for 20-45 mins). What do you think is the ideal feeding schedule for a breastfeeding-snacking baby; 2 hours, 2.5 hours or 3 hours? She only latches for not more than 5 minutes.
Thanks much.

I would try to keep to 2 hourly. IME the more DD had through the day, the less she'd have at night!
