Actually i will suggest to just buy 3months first. The rest like 6m onwards, you monitor your baby and fill up.
Why because, for example: my baby doesn’t have vomiting issue so I dont have to keep changing clothes.
But my baby grew from 10th percentile to 90percentile in a short period of time and thus many clothes that we thought he could wear, only managed to wear once and can put in storeroom already. Or that we forgot we have those clothes for him since we bought so long ago. Haha
Next, my baby has a habit of rubbing his feet until the socks will come off. So I can only get pyjamas that are fully covered for his toes.
So to your first question, dont get too many. Maybe 10 day time and 5 night time clothes will be good, the rest you slowly fill up after you monitor and observe your baby.
Then you must let them wear fully covered pyjamas. Cannot short sleeves and short pants. Cause they are still too small, better to be warm than cold.
