Why would this cause a baby's head to be flat more so than a normal crib?

My son got a flat spot from sleeping (only at night) in the Rock n Play and only for the first 3 months. It was because he favored one side of his head and would tilt his head only one way to sleep. In a crib, gravity would cause his head to fall to the side so he would be sleeping more on his ear, which is flat anyway since it's the side of the head. The RnP is on an incline and allowed him to keep his head more upright so that caused the flat spot. He's 2.5 yrs old now and I still feel the flat spot on his head with my hand. It's not severe but definitely noticeable.

I'm not sure, two of my kids used it & neither have a flat head. I'd check with your doctor.

As others said, maybe because it limits baby's ability to move freely. I noticed our little one has his head tilted down when he sleeps so its different position than a crib but it worked wonders for his acid reflux and he can sleep up 9 hrs in it. I think the important thing is to not overuse all the devices with baby on their backs like car seats, swings etc etc and that they get enough tummy time to avoid flat head.

I do not know exactly, but it is a little heavier than a conventional crib.

That only happened occasionally when my daughter fell asleep. Make sure if he is rear facing that before install you have reclined the seat all the way. Another thing we did to prevent this was adjust the height so that the head piece was more level with her head/ears; this actually seems to have fixed the problem with her head flopping forward because she can rest it to the side better.

I didn't use mine as a bedside bassinet for that reason. I let my baby sleep in it one night and she slid to the bottom and her little legs were all crunched up. I only used it during the day for naps.

I don't know about the other cribs. The sides are fixed and you just bend over. So far, it doesn't bother me at all to bend over.

The babies head goes on the higher end with the ridge all the way around. The lower part does not have a ridge all the way around.

I've used this mattress with my two year old since she was 6 mos and am using a second one with my three month old. So far, I've not had that problem. The mattress is flat.

I'm wondering about this as well...seems like it would have this issue. I just got one but am concerned about using it until my 4 month old can roll in all directions and right himself if need be.

Your welcome! One other thing of this highchair is that the back of the baby doesn't stay straight, that is one negative for me it stays a little inclined to the back, so baby's back also

It sits pretty upright and leans almost all the way flat. We've never used it fully upright with our baby.

If your baby turns into a tall toddler, his/her feet will be able to extend past the two-sided pad. The head and feet sides might be uncomfortable at that point.

The baby's head goes on the rounded part that is higher. The downward slope and open end allows for their little legs to move about

I bought this for out B-Safe carseat, because I thought it would be better support for a newborns head. After removing the insert and installing this one, we noticed that the head support was too high to support a newborn's head. It looks like if a baby was tall enough to fit in the head support, that they would be squished by the sides. I am disappointed in this product and will be returning it.

It needs to be rounded corners due to the way the mattress support frame attaches to the crib.

Have you tried aggressively pulling up on the center of the bottom of the crib? I've had this issue with mine too, but it's usually resolved by pulling up on the bottom (fairly high) and then latching the side. Kind of a weird mechanism.

I think they may clamp on the head to hard for a baby, also the foam is kind of firm. I wouldnt do it.

I'm not sure why, but ours does not fit snuggly at at all. It's very frustrating. I have about a 2 inch gap on both sides of the crib! I rolled up blankets to fill in the gaps, not ideal or really safe at all.
