I take mine out in a sleep suit and pramsuit
I learnt with my older too until they are 4 months old no point in buying tops dresses etc as they grow out of them really fast my youngest has baby grows that's for jammies and for 'clothes'
Just in whatever they’re wearing 🤷♀️ dress them up if it cheers you up if not a sleepsuit is fine
I always take my little girl out in babygrows, it’s more comfy for her xxx
