Review on Linda's Premium Monthly Milestone Blanket by Gary Bush

I bought this duvet in April and received LO on 31st August and unfortunately this happened to the duvet after a wash as advertised as the warranty has expired. How did I wash them in preparation? my LO and I haven't even used it yet and I'm disappointed with how well the stitching has held up after only one wash, especially as I bought a similar blanket from another seller but it has days, weeks, months and years on it documenting those milestones and it has held up great after just one wash and I have used it several times as I also planned to use both comforters as blankets and not just photo props. I'm sure this would be a quick fix but I'm not a seamstress and I'm a new exclusively breastfed new mom and I don't have time to play around with it which is why I gave it 3 stars.
