Weaning breastfeeding to milk

My little guy wont take a bottle from me and just keeps reaching for my shirt. Right now we have 4 feedings a day, when he wakes up at 430/5 am, morning nap, afternoon nap, and an hour before bed so around 6 pm.

Since the virus im working at home with the little guy and it doesnt look like ill return till august at the earliest (not really complaining since i love the time i have with him) but getting him to take a bottle is challenging

Currently he takes a bottle in the afternoon with dad, we started half and half but he will taked warm milk fine.

Im thinking about switching either the morning nap to a bottle or the prior to sleep one next, but afraid it may affect his sleeping at night.

Any recommendations on how to transition and get him off the boob? Weve talked about stopping all except the morning and just moving to a bottle and then take away the morning feed.

And advice is appreciated, sorry about the long post.
