I have a tall 2.5 year old little girl. She will not sit still long enough to eat a meal in her high chair anymore and really resists me putting her in it, I think she may be getting too big for it as when she is in it she seems really uncomfortable. I think she would eat better sitting at the table but obviously she is not tall enough and I really need a way to strap her in as well as she gets board of eating after 2 minutes and would escape if she wasn't strapped in. I've been thinking about getting a booster seats but most of them say they are only suitable for a child under two. Does anyone still use them for older children? We go on holiday in a few weeks so a travel booster seat would be ideal but I don't want to waste my hard earned cash if she's too big.
