My LO has started this strange habit at meal times of pushing on the highchair tray with both hands and making this whine/grunt sound. She will still continue to eat but if it gets bad I have to stop give her the spoon to play with or a sip of water and this seems to calm her and we can begin eating again or alternatively I take her out of the high chair for a minute and then put her back in. It starts at all different times throughout the meal - sometimes right at the start, sometimes in the middle and sometimes at the end. Is this just a developmental thing? I feel like she really wants to help feed herself and she loves holding the sippy cup. She makes a similar noise when she's playing lately too....it sounds to me like she's trying super hard to do something but her body just won't let her.
Any thoughts what might be going on?
