is celebrating LO 1 year old is a must?

Our boy is turning 1 in abt 1mth's time. We dun plan to have a big scale celebration as we dun think it is necessary. But we will be buying a small little cake n have a mini celebration at mil's house as they r excited tat baby is turning 1.. At first, we dun even wanna buy a cake. But upon seeing everybody's excitement n being happy for baby, we decided to get a cake n have a mini celebration just for mil's family at her hse. Nothing grand or fantastic. Afterall, itz juz a bday... juz take photos n keep it for memory.😊
