Need help altering babies' schedule (4 months old)

I'm hoping someone can offer some advice! My just turned four months old and will be starting cereal and fruit this month. I have them on a pretty good schedule and am not sure how to alter it to now incorporate feeding times for cereal/fruit. Here is their current schedule:

7 am: Bottle
7:30-8:30 Playtime
8:30ish - 10:30/11ish - Nap time
11:30 - Bottle
12-1ish - Playtime
1ish - 3ish - Nap
3:30 - Smaller Bottle
4-5pm - Playtime
5pm - 6:30 - Nap
6:45 - Bottle
7pm-8pm Playtime/Bath time
8pm - Sleep
They usually wake up by 11 pm and get another bottle before going down for the night. My son sleeps through the night but my daughter is usually up at some point (but doesn't eat).

How can I squeeze in cereal during the day? The pediatrician suggested giving the bottle first and then feeding cereal/fruit about an hour-hour and a half after - not sure how to do that since that's usually when they are napping.
Any advice?

My ped suggested giving the cereal mixed into fruit before breast or bottle feeding. Usually I give the fruit and cereal right before a diaper change since she gets all messy anyway then BF her.

I just started cereal this week with my 4 month old dd..my ped also told me to give it right before a bottle twice a day..he said the babies like to wash it down...it's working out well its just at the two times she gets it she dosn't take as much of the bottle

I would do the morning one at 8-8:15 ish and the cereal when they wake up from their nap. Then give them that bottle just before bed. Then top them off at 11pm.

This is close to what we did with my twins
