my lo is slowly making her way towards a 3.5 hr eating schedule. she is 4 months old and takes 5 ounces. she is now finally able to hold out a little past 3 hours (3:15-3:30 and 4 hours before her first feed of the day) should i also be increasing the amount she eats at the feed? should i give her 6 ounces. she still wakes at night for a dreamfeed and mid of night feed (which has been getting later and later the past week)
