Of course Ryn should not feel pressured to get her baby to sleep through the night, however, it is totally reasonable that she would want her baby to sleep at night (even if just a 5-6hr stretch), particularly if she is not getting sleeping herself during the day. Starting solids (and by solids I mean tiny amounts of rice ceral ONLY) could be absolutely out of the question for Ryn, however it does not hurt to consider all options. If Ryn's baby is unsettled at night it is important to look at whether he is in pain, hungry or unable to nod off on his own (maybe overtired or difficulty switching off without assistance). All reasons are vaild IMO. That fact that Ryn has to jiggle her baby all night to keep him from crying indicates that pain or hunger are more likey to be the reason.
