I bought something like this last week
http://www.tinydeal.com/wireles-baby...01-p-3601.html and I found that it is useful if I have no time to take care of the baby everytime. They are twins snowman, very lovely. I put one of them near the baby and I get the other one with me when the baby sleeps. If he wakes up and crys, the bell will ring to inform me about that, I can hear the cry from the baby, it is very convienient and useful, but one thing should be remembered, put the correct device near the baby, or you can not hear anything from the baby but the baby can hear you. I think that is very useful, has anyone also used something useful for the babycare and shares that with me?
