im the same lol i didnt have one, but my daughter was also im our room, plus so far we have only lived in small places ( moving soon yipeeee)
thing is i hear everything, i used to be a heavy sleeper but as soon as i had my daughter it was like i was only ever half asleep, did anyone else get that???
i would hear her every move, litterally!! she never cried in the night ever because i would always wake up when she first started stiring and go make her bottle just in time for her to wake, i think its a personal choice tho to be honest, we are moving in 4 weeks to a 3 bed house and baby due in 7 weeks! so i will definatly be buying one this time, as im going to put her down in her own room from 6-8 months, and if she is upstairs in bed and im downstairs i defo will need one!! you can get ones where you can see the baby now?? hehe
