Nickname help?

Not my baby this time, but my brother’s. I gave him a list of names I loved to help him with the process and he fell in love with this one, but now I would love to give him some nicknames options as well. I would love to go for a standard nickname even though nicknames are usually given with time (mine is “bebeca” and i don’t have any of these syllables on my name) for the name [name_f]Thais[/name_f] (ty-EES). This name is very hard to find a nice nickname and I can only think of [name_m]Ty[/name_m], T and [name_u]Izzy[/name_u]/[name_f]Izzie[/name_f], can you guys make something out of it? I don’t mind if it’s a big stretch.

The “ees” sound in [name_f]Thais[/name_f] made me think of [name_f]Easter[/name_f] which made me think of the nickname [name_f]Bunny[/name_f], though I think that’d probably only work as a family nickname. I don’t know if he’s thought of some middle names yet but the middle name could definitely help with nicknames. For example, [name_f]Thais[/name_f] [name_u]June[/name_u] could be TJ, [name_f]Thais[/name_f] [name_f]Lila[/name_f] could be [name_f]Tyla[/name_f], [name_f]Thais[/name_f] [name_u]Rae[/name_u] could be [name_u]Reese[/name_u].

I immediately thought of [name_m]Tiger[/name_m], which i think is adorable and very wearable - especially for [name_f]Thais[/name_f] as they share that first syllable.
Another I thought of is [name_u]Isa[/name_u], from the last syllable - which can often a nickname for [name_f]Isabel[/name_f]/la or a name in itself.

I think [name_u]Isa[/name_u] is the best option.

[name_f]Thais[/name_f] is pretty. I’d suggest [name_f]Taya[/name_f] (rhymes with [name_f]Maya[/name_f]) as a nickname.
