Baby Merlin sleep suit

So I know I'm about to jinx myself, but for the last four or five days, we have had a major improvement to night time sleep! I put my baby in the Baby Merlin Magic Sleepsuit and now at night he sleeps for an initial stretch of 6 hours on average. Before it was a four hour stretch max and then two hours and then an hour at a time. Now he will wake up once at night and then he will wake in the morning. I don't think it's coincidence! This suit worked with our daughter too. The size small says 3-6 months but the weight for the suit is 12 to 18 pounds so our son fits into it perfectly. Just wanted to share in case it helps anyone else. Our baby will be 8 weeks tomorrow.
