Clothing challenges. 2 months old wearing 6 months clothes.

So my LO is 2 months old. He started off not fitting in his newborn clothes. And just as we started with 1 month clothes, he started to outgrow those quick rapidly. So I have clothes in my house going up to 2 years, all hand me downs thankfully because I would be in shops every week.

At first, I pulled out 3months clothes...which he has outgrown. So I dug up to 6 months clothes. So the frustration is he doesn't even fit some of these. The chest is too short or the legs are too short. Now mind you these clothes are for 6 mo this old kids so they are big in size and small in length. His cousin wasn't even that fat. And worst, since they are for older kids, they ain't as easy to put on him as the new born clothes. I hate to fix his head in t-shirts. Newborn t-shirts have those buttons to widen the space. Then the onesies have no opening around the diaper area yet I don't want to have to completely undress LO for a diaper change.

Currently I am not sure which clothes fit. His wardrobe is a mess. I had packed away clothes away according to age and now I have to go throw all these to find out which clothes he can wear already. Unfortunately he already outgrew many of the 6 months clothes.
