My LO is 19 weeks on Saturday and about 15lb. She can hold her head up for long periods of time and is almost sitting up unaided. All her "chair" options are on the floor - bouncer, bouncy chair and boppy cushion. I think she would really love to be at more waist height with some toys while I'm busy in the kitchen etc rather than stuck on floor all the time. I cant really have her on the floor in there as the layout is such i will trip over her sooner or later so she has to sit in next room in view of me on floor. I've been given a lovely M&P prima pappa high chair which is for use from 6 months acc instructions. It also reclines. Would it be ok to put her in it? It has a harness etc. I honestly can't see what harm it would do esp if reclined but perhaps I'm missing something?? The seat is quite snug and I could always put a blanket etc if needed but I don't think it will be necessary.
