Egg free birthday cake

Very niche question but for those with little ones that have an egg allergy, if you are having a birthday party are you doing one egg free cake for everyone (baby and guests) or doing a small egg free cake for baby and normal cake for everyone else. Feel silly as I know baby will not care and the party is for us at this stage but I feel mean getting a cake he can’t even eat🙈 If anyone has any nice recipes or knows where sells a nice egg free cake that would also be lovely! So far we just don’t give him cake as he doesn’t need it but everyone needs cake on their birthday!
