I think it looks really cute! It is bright, sunny and generally happy! I tend to think around 5-6 he will want something "not so baby-ish" but why not wait until then to change it? Having a 6 year old boy myself - we are in that stage.

Do you really think daycare/preschool is going to be better? Or are you just upset with the in-laws because they don't have the same ideas you do? I have my share of in-law issues (mainly mil and sil). My fil and I had common ground in our love of the kids. We had our fair share of obstacles to overcome. Fil was a chain smoker, he taught my children to jump on beds and to examine tail pipes on cars. He was an inventor who had toxic chemicals and dangerous contraptions all over his house. Once he tried to put some experimental lubricating powders that he had developed for a client on ds's diaper rash. He taught my ds#1 to drink coffee. My fil absolutely loved my children, but he didn't always think things through. I had to work with him so he wasn't endangering my child. Instead of coming unglued the first time fil lit up that cigarette around my newborn baby, I took the baby from him and then said something like "Why don't you finish that and then you can hold the baby." Dh and I had to request that fil not operate his spray drier while we were visiting and we always had to be on the lookout for hazardous chemicals. DH and I hid his diaper rash concotion because we we not sure it wasn't a breathing hazard. How many parents want their kids jumping on beds or going behind cars to look at possibly hot tailpipes on a car that may soon be backing up? My fil passed away last year. My oldest ds was the love of his life. Unfortunately, fil only got to enjoy him for about three years and then he got sick. Fil never got to enjoy my other children like he did my oldest. I wish all of my kids had been able to know him. Do you really think your child is better off elsewhere? Or if there is something you can do to make the situation with your in-laws one that you can find mutually beneficial? I think you could get around the Barbie thing by just not allowing him to bring Barbie to their house. When he gets there, interest him in something else or just accidentally misplace or forget Barbie one day. Your son will probably figure out pretty quickly that he doesn't need Barbie when he is there. He can still play with Barbie at home. On the peeing thing, you can teach your ds that he can only pee outside when he is at the grandparent's house. Kids learn different rules, different houses pretty easily. My two oldest kids were in daycare when they were little. Our experiences weren't all positive. If you want daycare/preschool for the reason that you want him to have more interaction with other kids, you might try something like a 'Mom's Day Out' or see if you could get the in-laws to take him to activities like zoo or library pre-school hours. I wouldn't worry about whether he is learning his alphabet and numbers yet. He has plenty of time for that. You can jump start that learning by reading to him at night or singing songs in the car. In-laws situations aren't fun. I've got my share of problems with them. I would still try to make it work unless someone is being deliberatly nasty. Good luck!

Bright colors with lots of contrast are very good for developing eye coordination. Helping babies to focus etcetera. Primary colors are always good. Maybe paint the walls a cheerful yellow with bright red curtains and blue Linens Etc. I do know one young mother who painted her baby's room white with all black accessories. Her logic was that that was the highest contrast a person can get LOL.

White could work, but maybe you could find something that incorporated that chartreuse color. Do you have any ideas or themes you’re looking towards? I was thinking about that geometrical bedding. It reminds me of a rubix cube or tangram. Maybe you could use something along those lines to decorate the walls. Off the top of my head I’m thinking either framing or gluing some tangrams together to hang. Maybe a poster print from a rubix contest. I’ve also seen framing game boards or the box covers. That could expand your color options too. Tangrams
