How to set a proper meal schedule when my 9 months lo's napping time is not fixed?

First and foremost, a routine. A daily routine. Like for me, i wake up at 7.30am, clean house, send my son to school, come home and put baby to sleep at about 9.30am. He sleeps for an hour, then once he is awake ill cook lunch, by 11.30am feed baby. By lunch time me and hub eats. Play with baby and about 1230pm to 1.30pm baby has his afternoon nap till about 3 or 4pm etc. My son is 7 months old. Not comparing, but it is possible to fix up a rough gauge routine for both you and bub. You will realize that it will benefit both of you. Both of you will know what to expect, its stable for your lo too. Lids need a routine to feel safe and stable. Wheras for us mums, we know when we can rest. Lol
