I went through several sleep apps trying to find the right one for my baby and I found this one was the best, the baby shusher literally cut my time in half putting my son to sleep, before the I rocked, I let him cry it out, I sang and nothing worked or if any of them worked it would take an hour for him to settle it was a fight maybe 90 percent of the time.I combined the shush noise with rain noises and it not only settled my son but it helped him sleep better and get set in a routine which I was having a super hard time with, I still rock him but with this app I rock him for about 10-15 max he goes into a deep sleep and I put him in bad versus the full hour of rocking and singing I did before, he’s always been a good baby sleeping through the night which actually started aroun 13 months when he was starting to walk.This app is so great and worth every penny if you want to rock your son to sleep this is the best app for that also on a separate note:You are that child’s mother nobody knows better then you, if your child is 2 years d and still crying for you and not sleeping through the night don’t listen to your doctor and don’t just leave it I think if something like crying it out supposed to work I think age 2 should be the cut off point and you should try other ways such as not leaving the room, laying down with him reading a book, opening a projector with fish..Important note: Do not use this app if you are not rocking your baby to sleep and you let them “cry it out” use this app only if you used rain noises or sounds when they were infants, you can try but honestly I believe consistency is key and what you started you should continue, I’m not saying 100% it won’t work like it doesn’t hurt to try but just sharing my personal experience that rocking combined with relax melodies was way more helpful then just rocking alone.Also remember kids are not shoes one size doesn’t fit all and don’t compare your kids sleep routine to anyone else’s as long as your baby sleeping through the night, happy and healthy don’t listen to anyone including your doctor they there to give your child care and you medical advice they are not there to parent and they don’t have the bound you share with your son or know in your heart what your child needs don’t listen to them about emotional security and all that your child will feel secure in themselves emotionally when they know that their mother always tended to them a child that has a good bound and trust for their mom is something you gain by nurturing and trusting your gut feeling don’t get swayed by anything else.
