It's just constant - especially now we have a baby and MIL is going OTT with gifts (which we are grateful for but we sometimes get two of the same item from her in the same size for him because she's forgotten she's ordered it once already!)
Tbf it's not just baby stuff though. DH and I both have hoarding tendencies and before baby was born we had a good clearout (although still have tons of stuff we could get rid of) but it's the fact that every time we have a clear out it feels like we just end up overloaded with crap again.
Am currently sorting out baby's room to make it habitable (formerly our joint office - baby currently in our room) and I'm so ashamed of how bad it got. For most of the time we've lived here you couldn't even walk in. I'd attempted to tackle it a few times before I got pregnant just so I could work In there but I'd never have time to finish and then within a few months it would go back to being a hoarder's paradise.
We just constantly seem to accumulate crap. Whenever I think about it I have Mad Eye Moody's phrase in my head: constant vigilance!!
Long one I know but just needed to vent a bit and any tips welcome (and yes, I know I need to read Kondo!)
