Combo feeding + solids

Is anyone breastfeeding and giving formula as well while LOs having solids? When do you breastfeed and when do you give formula and how many ml formula do you give??? Will the formula affect his solid intake? I’ve been EBF for a couple months now but I want to wean off breastfeeding so would like to introduce formula again. Please advise on a good schedule for all 3. Thank you xxxx
