Baby more wakeful since starting solids!

My baby boy is ebf and gets solids twice a day. I usually do fruit and oatmeal in the morning and a veggie in the evening. His poops are regular but does seem a bit more gassy. He also has two bottom teeth already. I swear they say once baby starts solids they should be sleeping way better. He used to get up once a night. Go down at 7:30 and eat at 2:30 and then up for the day at 7:30-8. Now it’s every 2-3 hours. My question is would it be worth feeding him a bottle of formula before he goes down to bed? To help him stay asleep longer through the night. I can’t distinguish if he’s just waking up to comfort nurse or he’s actually hungry. Help! I would love my 5 hour stretch’s again 🤪
