My 3.5 month old baby has a feed every 2 to 2.5 hrs. After a feed she stays awake for 1.5 to 2 hrs and then we rock her to sleep in our arms. She sleeps for 30min or so and then it is time for her next feed and the cycle repeats. During the waking period we play with her but she gets cranky very soon and only calms down when we pick her up. Are we supposed to play with her all day? Dont they play on their own? Carrying her around all day is really really difficult. If yes, what games do I play with her? Even at night she gets up every 2 to 3 hrs (sometimes in an hour). But thankfully she takes a feed and immediately goes to sleep. Are we doing something wrong by picking her up every time she cries and rocking her to sleep in our arms? We really need some help and advise. Thanks
