Quick answer
Adjust your Mompush high chair whenever your toddler's shoulders sit above the tray, their knees bend awkwardly, or their feet dangle without support. Start with the seat and footrest, then recheck the tray and harness. Make one change at a time and test it at the next meal before adjusting anything else.
When to adjust your high chair
Toddlers grow in bursts, so a chair that fit last month can feel cramped this week. Watch for three signals: your child tries to climb out, their elbows hit the tray during meals, or their feet swing freely because the footrest is too low. Any of these means it is time to adjust the Mompush high chair rather than wait for the next growth spurt.
A good rule is to recheck the fit every two to three months, and again after any illness or growth spurt. If your toddler suddenly refuses the chair or slouches to one side, the seat or footrest is probably out of position. Fixing the fit usually solves the behavior before it becomes a habit.
Start with the seat and footrest
The seat depth and footrest position do most of the work in keeping a toddler stable. Their hips should sit back in the seat, knees should bend at roughly a right angle, and feet should rest flat on the footrest. If the footrest is too low, add a firm cushion under their feet as a temporary fix until you can move the footrest itself.
The Mompush Olli High Chair is designed for messy family meals, and its footrest position matters more than most parents expect. A supported foot gives your toddler leverage to sit upright, which makes self-feeding easier and reduces slouching. Move the footrest up one notch at a time, then watch a full meal before deciding whether it is right.
Tray and harness checkpoints
Once the seat and footrest are set, check the tray. There should be enough room for your toddler's hands to reach the tray surface without their elbows jamming against the sides. If the tray feels tight, move it forward slightly rather than pushing your child back into the seat.
The harness should sit snug across the shoulders and hips, with no more than two fingers of slack at the collarbone. A loose harness lets a determined toddler slide forward or stand up, so tighten it after every adjustment. Never rely on the tray alone to keep your child in the chair.
Step-by-step adjustment
- Loosen the harness and remove the tray: Unbuckle the harness and set the tray aside so you can reach the seat and footrest without obstruction. Common mistake: adjusting the footrest while your toddler is still strapped in, which makes it hard to judge their posture. Checkpoint: your toddler should be able to sit back with their hips against the back of the seat.
- Set the footrest height: Move the footrest up or down so your toddler's knees bend at about a right angle and their feet rest flat. Make one notch change at a time. Common mistake: raising the footrest too high, which pushes the knees up and makes the seat feel cramped. Checkpoint: feet flat, knees bent, no dangling.
- Recheck the seat depth and recline: If the seat has an adjustable depth or recline, set it so your toddler's back stays supported without slouching. Common mistake: leaving a deep recline meant for infants, which lets a toddler slide forward. Checkpoint: back supported, no sliding.
- Reposition the tray: Slide the tray forward or back so your toddler can reach it comfortably without their elbows hitting the sides. Common mistake: pushing the tray too close, which traps their hands and causes frustration. Checkpoint: hands reach the tray, elbows clear.
- Tighten the harness and test the fit: Fasten the harness snug across the shoulders and hips, leaving no more than two fingers of slack. Common mistake: leaving the harness loose because it feels restrictive, which lets a toddler stand up mid-meal. Checkpoint: snug harness, no slack at the collarbone.
