Has anybody else's LO's had any trouble with tummy-time? My daughter just hit 5months old (she is a premie and was 6 1/2 wks early) and has never liked doing tummy time; looking for some advice/tips/suggestions/comments (LOL). I have tile floor so I've either set her up on my bed or a yoga mat laying tummy down with her arms over a nursing pillow (1 of those half moon shaped ones, i cant think of the name atm). She'll lay on her back and play but only lasts about 6/7 mns before she gets upset😔
