Cot - baby only slept in it for a few hours. And since I’m breastfeeding, it’s easier to cosleep on the bed with me (I do not have enough space to put baby next door or something). Too much clothings - Some either forgotten about it or not enough time to wear unless I change her 5-6 times per day like fashion show. Baby hand sanitizer - I ended up using the adult ones, so my baby sanitizer is as good as buy to display. The rest of the things I find unnecessary but may not be the case for you since we use different stuffs. But above is the top 3 that I would totally not buy again for my next baby 😅.
Baby clothes before 9 months. They grow so fast. Luckily the 2nd one is coming soon so can ROI.
