Feeding frequency during the day and night by milk type. (A) Daytime feeding frequency by child age and feeding type. (B) daytime feeding frequency by child age and feeding method in the bottle feeding only subgroup. (C) nighttime feeding frequency by child age and feeding type. (D) nighttime feeding frequency by child age and feeding method in the bottle feeding only subgroup. Poisson regression was conducted to assess the effect modification of child age on the frequency of daytime and nighttime feeding across different methods and types of feeding
